INSTALLATION INSTRUCTIONS Cont...
For best venting performance, here are some general venting rules that we recommend:
1. Use only Archgard, Simpson Dura-Vent or Metal-fab direct vent systems and components.
2. Maintain a minimum of 1” (26 mm) clearance to combustibles from the outside surfaces of
vertical vents and minimum of 1” (26 mm) sides and bottom, and 2” (51 mm) from top
surfaces of horizontal vents.
3. Observe any local code restrictions, if any, regarding the installation of this type of gas
appliance.
4. Observe the venting chart given in this manual.
5. Use vent spacers between the inside and outside vents at 3 ft (915 mm) intervals (Archgard
vent kits only).
6. Never slope horizontal vents downwards.
7. Maintain at least a rise of 1/4” (7 mm) for every 1 ft (305 mm) of horizontal vent.
8. Terminate the vent with a vent termination cap (for horizontal terminations) supplied by
Archgard Part # TK-1 or (for vertical terminations) Simpson Dura Vent or Metal-fab.
9. Support horizontal vents every 3 ft (915 mm) to prevent it from sagging.
