Ignition Systems

Modofire fire features are available with several ignition systems based on burner output, installation requirements and the desired level of automation.

Battery Push-Button / Match-Lit | Standard (SC) and High Capacity (HC)
A simple, manually operated system requiring no electrical connection. The gas valve is opened by hand, and the burner is lit using either an integrated battery-powered spark igniter or a long-reach lighter. This option does not provide automatic flame monitoring or relighting. Flame height is adjusted manually using a keyed valve on the side of the fire feature.

Battery Flame-Sense | Standard Capacity (SC), Up to 250K BTU
A battery-operated flame-sensing system requiring no electrical connection. It provides convenient push-button ignition, continuous flame monitoring and automatic gas shutoff if the flame is lost. Flame height is adjusted manually using a control dial on the side of the fire feature.

Electronic Flame-Sense | Standard Capacity (SC), Up to 250K BTU
A fully automatic electronic ignition system with continuous flame monitoring, automatic relighting and safety shutoff. It can be integrated with switches, timers, remote controls and compatible home-automation systems. Flame height is adjusted manually using a keyed valve on the side of the fire feature.

Electronic Flame-Sense | High Capacity (HC), Over 250K BTU
Designed for higher-output burners and available only with electronic ignition. It provides fully automatic ignition, continuous flame monitoring, automatic relighting, safety shutoff and home-automation compatibility. High-capacity ignition is recommended for higher-BTU applications, although it may not be required for every burner configuration. Flame height is adjusted manually using a keyed valve on the side of the fire feature.

Very High Capacity (VHC) electronic ignition systems for burner outputs up to 640K BTU are also available.

Modofire uses premium ignition systems from Warming Trends, HPC, The Outdoor Plus, Firegear and other leading manufacturers. Each system is selected and configured for the burner, BTU output and installation requirements of the individual fire feature.

Fire Media

Fire glass, lava rock, and alternative media are sold separately. Select Modofire models include rolled lava rock where required to maintain warranty coverage.

Shipping & Lead Time

Lead times. Most Modofire products are made to order. Quoted production and shipping dates are estimates, not guaranteed delivery dates. Lead times vary with the design, finish, components, and fabrication schedule. We will communicate material changes to the expected shipping schedule. Transit time begins when the carrier receives the shipment.

Shipping and delivery. Products ship from Modofire or our domestic fabrication partners. Shipping method and cost depend on the size, weight, destination, and delivery requirements of the order. Smaller items generally ship by parcel carrier. Large or custom pieces generally ship crated by freight for curbside delivery, with a liftgate when included in the shipping arrangement. Delivery does not include placement, uncrating, assembly, gas or electrical connections, or installation.

Site readiness. The customer is responsible for providing an accurate delivery address, suitable carrier access, and people and equipment needed to receive and move the product from the delivery point. Storage, redelivery, or special-handling charges caused by unavailable access or a missed delivery appointment are the customer’s responsibility. Schedule installation only after shipment has been confirmed and the product has been received and inspected.

Delivery inspection. Inspect the crate and packaging before signing. Note any visible damage on the carrier’s delivery receipt, take photographs, and contact Modofire promptly. If damage is discovered after uncrating, retain the packaging and contact us with photographs as soon as possible, preferably within 48 hours. We will help review the issue and coordinate the appropriate freight claim or resolution.

Delays and related costs. Modofire is not responsible for carrier delays, weather, permitting, site conditions, or other circumstances outside its control. To the extent permitted by law, Modofire is not responsible for costs arising from a delayed delivery, including scheduled installers, equipment, travel, or lost use.

Warranty & Coverage

Each Modofire fire feature is made to order. We stand behind the quality of its materials, fabrication and finish.

Modofire covers the vessel, enclosure, fire table or sculpture against defects in materials and fabrication for five years from delivery. Powder-coated finishes are covered for five years from delivery against premature peeling or blistering caused by application or adhesion defects. This coverage applies to the original purchaser.

Burners carry a lifetime manufacturer’s warranty, subject to the manufacturer’s terms. Lifetime coverage applies only to the burner. Ignition systems, controls and other components carry separate manufacturer warranties. Modofire will help coordinate claims and connect you or your service professional with technical support.

Installation, gas and electrical connections, startup and service must be handled by qualified local professionals. Approved fire media must be installed before regular use according to the burner manufacturer’s instructions. Keep pilot openings, drainage and ventilation clear. Qualified installers may test the system without media when permitted by the manufacturer.

Modofire’s warranty does not cover:

• Normal wear or expected cosmetic changes such as patina, fading, heat discoloration or surface rust.
• Scratches or chips caused during handling or installation.
• Damage from improper installation, incorrect media placement or overheating.
• Damage from blocked ventilation or drainage, standing water, misuse, modification or inadequate maintenance.

Clean powder-coated surfaces with mild detergent and a soft cloth. Rinse thoroughly and remove salt or chemical buildup. Do not use abrasive cleaners or harsh solvents.

To make a claim, contact Modofire with proof of purchase, photographs and a description of the issue before returning any part. Modofire will repair or replace covered vessel or finish defects at its discretion. Removal, reinstallation, on-site labor, freight and related costs are not covered by Modofire’s warranty. Component claims follow the applicable manufacturer’s warranty terms and process.

Maintenance & Care

Modofire powder coated aluminum fire tables are built for long-term outdoor use and require only routine maintenance.

Clean Surfaces
Wash with mild soap and water using a soft cloth. Avoid abrasive cleaners, solvents, bleach, and pressure washing. In coastal or poolside environments, clean more frequently to preserve the finish.

Burner Care
Keep burner ports free of leaves, insects, debris, and fire media dust. Clean gently with a soft brush or compressed air. Do not modify the burner. Install fire media loosely and evenly for proper flame performance.

Ignition Systems
Periodically inspect gas connections, wiring, controls, and ignition components. Keep electronic systems dry and allow them to dry completely if exposed to moisture. Test operation regularly and follow the ignition manufacturer's maintenance recommendations.

Covers & Lids
Always allow the fire table to cool before installing a lid or cover. Keeping the unit covered when not in use helps protect the finish and extends the life of the burner and ignition system.

Seasonal Inspection
Before each season and after extended storage, inspect the burner, gas connections, and ignition system. Replace worn components as needed and consult a qualified professional for service.

With routine cleaning and periodic inspections, your Modofire fire table will provide years of dependable performance and lasting beauty.

Gas & Electrical Requirements

To help ensure proper performance, your fire feature will require an adequate gas supply and, depending on the ignition option selected, may require electrical power.

Gas Supply Requirements

Available for Natural Gas (NG) or Liquid Propane (LP). Most installations connect to an existing gas line or an external propane tank.

Most residential fire features operate between 90k and 300k BTU. Larger fire tables and commercial installations may require 300k BTU to 600k+ BTU.

As burner size increases, larger gas lines and sufficient gas supply become increasingly important.
