WARNING:
- Follow the venting instructions exactly for safe and proper appliance operation.
- Use Mill Pac or high temp RTV silicone for all venting connections.
- Risk of fire, explosion, or asphyxiation if improper venting setup.
-Risk of fire, do not allow loose materials or insulation to contact vent pipe. Remove
insulation to allow installation of thimble and maintain clearances to combustible
materials.
This appliance uses either a 8" x 11" or 5" x 8" vent pipe system. For safe and proper operation of the
appliance follow the venting instructions exactly. Deviation from the minimum vertical length can create
difficulty in burner start-up and sooting. Allow several minutes for the flame to stabilize after ignition under
extreme vent configurations. It is recommended for vent lengths that pass through unheated spaces
(garages, attics, crawl spaces) be insulated to minimize condensation. Use at least three (3) screws at each
vent connection. Check periodically that the vents are unrestricted, especially the exterior vent cap.
