Elevated Air Supply
A safety system designed to burn off excess or unusable gases at high elevations, minimizing fire hazards.
Note:
Reduced & Low Noise
An insulated design targeted satisfaction of site noise requirements. The Reduced Noise is partially insulated, making it a more cost-effective option when extreme noise reduction is not required.
The Low Noise design is fully insulated with the addition of a baffle plate. This design is the most effective noise reduction that Flameco has to offer. This is the ideal choice when the operational site is near local communities.
Note:
Air Control
A pneumatic push-pull, or rotating, system that controls the primary air flow draft. This is the design to choose when you want to optimize draft through air supply while also reducing the number of start-up cycles.

6” x 6” Access:
Enables easy access to internal piping, main burner, and pilot assemblies.
Lifting Lugs:
Provide additional safety and stability with transporting, mounting, or securing the burner. This option is recommended when the burner is to be mounted more than 4 ft from the ground.
Manway:
Manway covers are attached by nuts & bolts, providing easy access to internal components.
Purge Fan:
Purge fans push air through the firetube and stack, eliminating residual gas.
Transformer Bracket (XFMR):
Transformer Brackets (XFMR) are made to mount inside the housing.
Ignition Module Bracket:
Ignition module brackets securely mount burner management systems for reliable installation.
Quick-Clamps:
This design was created to provide technicians with ease of access to burner internals. Rather than nuts and bolts, quick-clamps are welded to the housing for seamless maintenance process.
UV Sight Tube:
The UV Sight Tube enables automatic flame monitoring for the burner.
Welded Flange Nuts
Aluminum nuts are welded inside the housing for ease of mounting and removing the flame arrestor. This option is selected when ease of access is a priority to field and service technicians.
ADD-ON OF NATURAL DRAFT BURNER

Plate Flange:
Mounting flange adapter that connects the burner flange to unique customer requirements.
Extension Nipple:
A custom threaded pipe to extend the nozzle/flame into the firetube to the proper and safe depth. Ask for this addition when the nozzle is not placed within the bath solution (4" - 6".)
Extension Spool:
A mounting spool that is used to extend the flame arrestor past an obstruction. Recommended when the stack overhang exceeds the standard or when retrofitting the current unit.
Manual Secondary Air Control Spool:
Control secondary airflow going into the firetube. This product is aimed at retaining heat in the firetube and reducing cycle times.
Return Flue Gas:
Ideal for units that have the intention of returning Flue Gas for reuse. This product is also recommended for extreme weather conditions.
Threaded Vent Arrestor
Designed for end-of-line vertical venting, this arrestor enables unrestricted airflow while providing flame protection for storage tanks and atmospheric vent lines. Ideal for low-pressure systems, it prevents flame ingress without impeding normal breathing and venting operations.
Gasket:
Recommended for all flange connections. The Gasket provides a seamless seal aimed at preventing air or liquid from entering or exiting the flange connection.
