SECTION C: Installation

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

Termination

The flue direct vent cap MUST be mounted on the ex- terior of the building. The direct vent cap cannot be installed in a well or below grade. The direct vent cap must be installed at least 1 ft above ground level and above normal snow levels. The Raypak-approved stainless steel flue direct vent cap must be used (sales order option D-15). The vent terminal must be located NO CLOSER than 12” off the wall.

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

Direct Vent - Vertical

Fig. 25: Direct Vent - Vertical

CAUTION: This venting system requires the installa- tion of a condensate drain in the vent piping per the vent manufacturer’s instructions. Failure to install a condensate drain in the venting system will void all warranties on this heater.

Installation

These installations utilize the heater-mounted blower to draw combustion air from outdoors and vent combus- tion products to the outdoors.

The total length of air supply pipe cannot exceed the distances listed in Table K. 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 Table K.

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 jeopard- ize 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).
