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 self-venting when installed with the optional factory-supplied outdoor vent kit and re- quire no additional vent piping. A special vent cap, flow switch cover and air intake hood are provided in accor- dance with CSA requirements, which must be installed directly on the heater. Correct clearances can be found earlier in this section.

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 D-11).

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.

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 manu- facturer in accordance with its listing (sales order option D-11).

Freeze Protection

When installing this heater in an outdoor location that is susceptible to freezing, sales order option B-22 must be ordered. The B-22 option energizes the heater pump at a preset temperature drop to circulate water and reduces the possibility of freezing and dam- aging the heat exchanger or headers.

Controls

WARNING: Installation, adjustment and service of heater controls, including timing of various operating functions, must be performed by a qualified installer, service agency or the gas supplier. Failure to do so may result in control damage, heater malfunction, property damage, personal injury, or death.

WARNING: Turn off the power to the heater before installation, adjustment or service of the CPW board or any heater controls. Failure to do so may result in board damage, heater malfunction, property dam- age, personal injury, or death.

CAUTION: This appliance has provisions to be connected to more than one supply source. To reduce the risk of electric shock, disconnect all such connections before servicing.

3.Do not locate adjacent to any window, door walk-

 

way, or gravity air intake. The vent must be lo-
