Product Usage Instructions
Before using the HELIFIRE 360 Surface Mount Power Vent Kit, ensure that you have read and understood the Installation and Operating Instructions supplied with the fireplace. Keep these instructions together with those supplied with the fireplace for reference. Follow the steps below for proper usage of the product:
- Ensure that the exhaust outlet is positioned lower than the side of the vent indicated by the arrow to prevent rainwater from entering and collecting in the outlet. The outlet must have a clearance of 36 inches in front of it before the exhaust comes into contact with any material.
- The product can be used in a flat roof or peaked roof configuration, depending on your requirements.
- The product must be installed with a riser (minimum height of 12 inches) as required by local codes.
- Flexible aluminum venting can be used for the product’s installation.
- Ensure that all minimum clearances are maintained as per Figure 4. The minimum clearance to a window or door that may be opened is 12 inches, and the minimum clearance to a permanently closed window is also 12 inches to prevent condensation on the window.
- Ensure that the product is installed at least 6 feet away from a mechanical air supply inlet, and 7 feet away from a gas meter.
- Ensure that the product is installed at least 12 inches away from a non-mechanical air supply inlet to the building or the combustion air inlet to any other appliance.
- The minimum venting length to the power vent is 1.5 feet.
- Ensure that all installation and operating instructions are followed for proper gas supply, safety requirements, and operating instructions.
IMPORTANT: THESE INSTRUCTIONS ARE TO REMAIN WITH THE HOMEOWNER.
These instructions are supplementary to the Installation and Operating Instructions supplied with the fireplace and should be kept together. Refer to the Installation and Operating Instructions for proper gas supply, safety requirements and operating instructions.
Dimensions
Venting Configurations
NOTE: If using the Surface mount power vent, the exhaust outlet must be positioned so that it is lower than the side of the vent indicated by the arrow. This is to prevent rain from entering and collecting in the outlet. The outlet must have a clearance of 36 inches in front of it before the exhaust comes into contact with any material.

Power Venting Clearances
- Surface mount power venting outlet must have a minimum of 36 inches clearance between the front of the outlet and any other material.
Electrical Connection
Combustion Air Intake Restrictor
The air intake restrictor regulates the incoming air flow in order to achieve the desired flame appearance. The desired flame appearance is one in which the flame extends to fill the length of the firebox (approx. 55”). The position of the restrictor corresponds to the length of venting between the air intake and the firebox. More airflow will be required as the length of venting is increased (to a maximum of 50’) and less airflow will be required if the venting length is shorter. The installer must keep in mind that too much air flow will make it difficult for the gas in the firebox to be ignited and remain lit, while not enough airflow will produce a shorter, weaker appearance.
To adjust the airflow
- With the Helifire 360 lit, observe the length of the flame. If the flame is too short, allow more airflow to enter the venting by loosening the adjustment screw at the front of the intake venting and move the screw downwards in its slot before tightening the screw up. This will open the restrictor. Conversely, if the Helifire 360 has difficulty lighting or staying lit because of a short venting distance, loosen the adjustment screw and move the screw upwards in its slot. This will reduce the airflow by closing the restrictor.
- Observe the flame again. As these adjustments are guidelines, it may be necessary for the installer to repeat the cycle of observation and adjustment.
Venting
Exhuast venting options
The Helifire 360 has three exhaust venting options. The default exhaust position is at the exhaust end of the Helifire 360. The other two are at the left and the right sides of the Helifire 360 (Figure 9).
To change exhaust vent position
- Remove the flue collar from the exhaust end of the Helifire 360.
- Remove the cover plate from the desired side of the Helifire 360 and secure the flue collar to that opening.
- Secure the left over cover plate to the exposed opening.
Note: The intake vent has only one position which is at the opposite end of the Helifire 360 body.
Power venting – flexible venting connection
Use supplied hose clamps to secure the flexible venting to the power venting collar. For additional security, apply at least one self tapping screw through vacant screw slots on the band. This will ensure that the venting never works its way off of the collar.
Venting through combustible ceiling or floor
- Fire stops are used to protect combustible floor, ceiling and wall material from open flame present outside of the unit.
- They surround the flexible venting material as it passes through combustible material.
NOTE: 1 pair of Firestop come with the Flush mount vent kit. Use as many firestops as is necessary to maintain a 1/4 inch clearance between the flexible vent and any combustible material throughout the length of the exhaust portion of the flexible vent. If additional firestops are required, packages of 2 pair can be ordered through a Town & Country Retailer.
Stud Supports
Stud supports for 2×6 studs are used to guide the flexible venting from the fire feature venting collar to the power venting exhaust. Use stud supports to maintain the structural integrity of the supports and to keep the venting from unnecessary movement. These supports can also be used to guide the venting through a floor or ceiling. To install, cut out a 4 5/8” section of a stud and fasten two supports to each stud. The Helifire 360 comes with 4 pairs of supports. Additional supports can be ordered.
NOTE: 4 pair of Stud Bracket Supports come with the surface-mounted power vent kit. Use as many supports as is necessary to maintain a 1/4 inch clearance between the flexible vent and any combustible material throughout the length of the exhaust portion of the flexible vent. If additional stud supports are required, packages of 4 pair can be ordered through a Town & Country.
Vent Stand-Offs
Vent stand-offs (Figure 15 and Figure 16) are used to maintain a 1/4 inch gap between combustible surfaces and the flexible venting material. The flexible venting material may come into direct contact with noncombustible material such as rockwool or cement board.
NOTE: 20 vent stand-offs come with the surface mounted power vent kit. Use as many stand-offs as necessary to maintain a 1/4 inch clearance between the flexible vent and any combustible material throughout the length of the exhaust portion of the flexible vent. If additional stand-offs are required, packages of 20 can be ordered through a Town & Country Retailer.
