After the heater has been properly suspended in 
accordance with the preceding headings of this sec-
tion, proceed to install the venting as described 
below (See Page 23, Figure 16):

1. Using a tape measure, measure the distance from 

the floor to the center of the vent collar on the rear 
surface of the burner. Note this dimension here 
__________.

2. Using the tape measure, transfer this measure-

ment to the inside surface of the exterior wall that 
the vent will penetrate; make a reference mark. 
Check the location of the hole to ensure that there 
are no internal wall structures (i.e. studs) to pre-
vent penetration. Also check that the outlet of the 
vent does not compromise the general venting 
requirements, See Section 5.1.

3. Using the tape measure, measure the distance 

between the rear surface of the heater and the 
exterior wall. Note this dimension here _________.

NOTE: If the distance between the rear surface of 

heater and the exterior wall is greater than 5' 
(1.5 m), a 5’ (1.5 m) balanced flue vent exten-
sion kit (P/N 08039000) will be required.

4. From the reference mark made in step 2, measure 

down vertically 1/4" (6 mm) per foot measured in 
step 3. Cut 5” (125 mm) vent terminal clearance 
hole at the lower reference.

5. Install 3" (80 mm) flue pipe from the vent collar, on 

the rear surface of the burner, and through the 
exterior wall. Be sure to seal any joints in the 3" (80 
mm) flue pipe with high temperature silicone seal-
ant and secure them with three sheetmetal screws.

IMPORTANT: The 3" (80 mm) flue pipe must extend 

a minimum of 6" (150 mm) beyond the 
exterior surface of wall/fresh air intake.

6. Assemble or cut the 5" (125 mm) air supply pipe to 

run between the vent collar on the rear surface of 
the burner and the outside surface of the exterior 
wall. Be sure to seal any joints in the 5" (125 mm) 
air supply pipe with high temperature silicone seal-
ant and secure them with three sheetmetal screws.

7. From the exterior of the building, slip the assem-

bled or cut 5" (125 mm) air supply pipe over the 
installed 3" (80 mm) flue pipe. Connect the 5" (125 
mm) pipe to the vent collar on the rear surface of 
the burner with high temperature silicone sealant 
and secure the connection with three sheetmetal 
screws.

8. From the exterior of the building, slip the vent ter-

minal onto the 3" (80 mm) flue pipe and guide the 
sleeve portion of the vent terminal over the 5" (125 
mm) air supply pipe that is flush with exterior sur-
face of wall. Secure air vent pipe to the vent termi-
nal collar with silicone sealant. 

9. Secure the vent terminal to the exterior surface of 

the wall.

 NOTE: If the protruding 3" (80 mm) flue pipe is 

directly below and within 24" (609 mm) of the 
building soffit, the optional vent extension 
should be used.
