FURNACE VENTING INSTALLATIONS

READ AND FOLLOW ALL INSTRUCTIONS IN THIS SECTION. FAILURE TO PROPERLY
VENT THIS FURNACE CAN CAUSE CARBON MONOXIDE POISONING OR AN EXPLOSION
OR FIRE RESULTING IN PROPERTY DAMAGE, PERSONAL INJURY OR LOSS OF LIFE.
9.4.1 NON-DIRECT VENT INSTALLATION USING INDOOR COMBUSTION AIR (ONE PIPE
SYSTEM)
Non-direct vent installations require only a vent pipe. This may be desirable when using outdoor combustion
air is not practical.
• Provisions are not made for routing of combustion air;
• The outdoor environment may contain contaminants undesirable for combustion.
• Install and secure a 8" (20 cm) piece of intake air pipe with a 90° elbow to prevent objects from
entering burner area, and or objects from blocking combustion air intake.
9.4.2 DIRECT VENT INSTALLATION USING OUTDOOR COMBUSTION AIR (TWO PIPE
SYSTEM)
The direct vent confi guration is the preferred installation method. The primary advantages are:
• No special kit or modifi cations are required for direct vent installations
• Dedicated combustion air and vent piping eliminates the need to use already heated air for combustion
purposes;
• The probability of corrosive contaminants being present in the combustion air is greatly reduced;
• The direct vent confi guration is unaffected by any other appliances, exhaust fans, or other devices that
tend to create negative pressure conditions while operating.
• No vents for combustion and ventilation air are required in confi ned spaces.

9.4.3 COMBUSTION AIR

This furnace is certifi ed as a Category IV Type FSP Non-Direct and Direct Vent Furnace. When installed
as a direct vent furnace, all combustion air is supplied from the outdoors via the plastic piping system. All
components are fi eld supplied, except for the 2" PVC connector used to connect the combustion air piping to
the furnace.
The combustion air piping, like the exhaust piping, must be air tight throughout the system. The adapter joining
the combustion air to the furnace is supplied with one gasket.
IMPORTANT
IF PLANNING TO USE ABS PIPE FOR AIR INTAKE, USE AN ALL-PURPOSE CLEANER
AND ABS TO PVC TRANSITION CEMENT. IF PLANNING TO USE CPVC PIPE, USE
AN ALL-PURPOSE CLEANER, A CLEAR OR PURPLE PRIMER AND ALL-PURPOSE
CEMENT APPROVED FOR THE PURPOSE.
ADDITIONAL INFORMATION ABOUT CLEANERS, PRIMERS, SOLVENTS AND
CEMENTS MAY BE OBTAINED FROM THEIR MANUFACTURERS.
IF THE FURNACE IS TO BE INSTALLED IN THE VICINITY OF OTHER FUEL BURNING
APPLIANCES, ADEQUATE COMBUSTION AIR MUST BE AVAILABLE FOR THE NON-
DIRECT VENT APPLIANCES. SEE SECTION 8.1, "DETERMINING COMBUSTION AIR".
