Flues supported only by flashing and extended above the roof more than 5 ft should be securely guyed or braced to withstand snow and wind loads.
The air inlet opening MUST be installed 1 ft above the roof line or above normal snow levels that might ob- struct combustion air flow. This dimension is critical to the correct operation of the heater and venting system and reduces the chance of blockage from snow. The vent cap must have a minimum 3 ft vertical clearance from the air inlet opening.
Outdoor Installation
Outdoor models are
Care must be taken when locating the heater out- doors, because the flue gases discharged from the vent cap can condense as they leave the cap. Improper location can result in damage to adjacent structures or building finish. For maximum efficiency and safety, the following precautions must be observed:
1.Outdoor models must be installed outdoors and must use the outdoor vent cap, flow switch cover and air intake hood available from the manufac- turer (sales order option
2.Periodically check venting system. The heater’s venting areas must never be obstructed in any way and minimum clearances must be observed to prevent restriction of combustion and ventilation air. Keep area clear and free of combustible and flammable materials.
3.Do not locate adjacent to any window, door walk- way, or gravity air intake. The vent must be located a minimum of 4 ft horizontally from such areas.
4.Install above grade level and above normal snow levels.
5.Vent terminal must be at least 3 ft above any forced air inlet located within 10 ft.
6.Adjacent brick or masonry surfaces must be pro- tected with a
NOTE: Condensate can freeze on the vent cap. Frozen condensate on the vent cap can result in a blocked flue condition.
NOTE: The vent cap, flow switch cover and air intake hood must be furnished by the heater manufacturer in accordance with its listing (sales order option
