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 follow ing precautions must be observed:

1.Outdoor models must be installed outdoors and must use the outdoor vent cap and air intake hood available from the manufacturer (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.

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 rust-resistant sheet metal plate.

NOTE: The vent cap and air intake hood must be furnished by the heater manufacturer in accordance with its listing (sales order option D-11).

NOTE: Condensate can freeze on the vent cap. Frozen condensate on the vent cap can result in a blocked flue condition.

Freeze Protection

The Raypak electronic temperature control includes a freeze protection feature. In the event the temperature drops below 40°F at any of the boiler temperature sen- sors, the pump is turned on and will remain on until the temperature at all boiler sensors rises to 45°F.

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 any heater controls. Failure to do so may result in board damage, heater malfunction, property damage, 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.

CAUTION: Risk of electric shock: More than one disconnect switch may be required to de-energize the equipment before servicing.

The Raypak electronic temperature control is pro- vided to maintain the desired system water temperature. The control has various modes of opera- tion which are described on the following pages.

To minimize short cycling, locate the system (target) sensor as follows:

Setpoint: The intended system supply temperature.
