The total length of air supply pipe cannot exceed the distances listed in Tables L and N. Each elbow used is equal to 10 ft of straight pipe. This will allow installation in any arrangement that does not exceed the lengths shown in Tables L and N.

The vent cap is not considered in the overall length of the venting system.

Care must be taken during assembly that all joints are sealed properly and are airtight.

The vent must be installed to prevent the potential ac- cumulation of condensate in the vent pipes. It is required that:

1.The vent must be installed with a condensate drain located in proximity to the heater as directed by the vent manufacturer.

2.The vent must be installed with a slight upward slope of not more than 1/4 inch per foot of hori- zontal run to the vent terminal.

3.The vent must be insulated through the length of the horizontal run.

Termination

The vent cap MUST be mounted on the exterior of the building. The vent cap cannot be installed in a well or below grade. The vent cap must be installed at least 1 ft above ground level and above normal snow levels. The vent cap MUST NOT be installed with any com- bustion air inlet directly above a vent cap. This vertical spacing would allow the flue products from the vent cap to be pulled into the combustion air intake installed above.

This type of installation can cause non-warrantable problems with components and poor operation of the heater due to the recirculation of flue products. Multi- ple vent caps installed in the same horizontal plane must have a 4 ft clearance from the side of one vent cap to the side of the adjacent vent cap(s).

Combustion air supplied from outdoors must be free of particulate and chemical contaminants. To avoid a blocked flue condition, keep the vent cap clear of snow, ice, leaves, debris, etc.

WARNING: No substitutions of flue pipe or vent cap material are allowed. Such substitutions would jeopardize the safety and health of inhabitants.

The stainless steel flue direct vent cap must be fur- nished by the heater manufacturer in accordance with its listing (sales order option D-15).

Outdoor Installation

Outdoor models must be vented with listed vent mate- rial per the following instructions and installed with the optional factory-supplied outdoor vent kit. A special vent cap and air intake hood are provided in accor- dance with CSA requirements. These must be installed directly on the vent pipe as illustrated in Fig. 29.

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 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).
