Not all outdoor areas will have power supplied for the ease and safety of electronic ignition use- but flame sensing in your area may be required by code or you just prefer that peace of mind. The certified Push Button / Flame Sensing line allows both the convenience of push-button ignition with the safety of flame sensing. Lighting the fire is as simple as pushing a button- flame height is fully adjustable via control knob. If the flame blows out the system safely turns off gas. Certified by CSA to meet most building code requirements.
