All installations and services must be performed by qualified service personnel.

the conclusion of the vent pipe installation. This will insure a leak free return air compartment. Refer to Figure 6A.

Figure 6A.

NOTICE: The exhaust vent pipe must be supported every 4 feet. After making sure the length of the piping is correct glue all connections in place.

: This CMA/CMC furnace has been designed to be installed as a direct vent system and must have its combustion air brought in from outside the conditioned space. The failure to install the vent/air intake system as specified in these instructions will void the heat exchanger warranty and may result in property damage, personal injury or loss of life.

NOTICE: The furnace model series CMA/CMC may be vented either through the sidewall or the roof. For sidewall instructions, continue to the following section. For roof venting, refer to Section IV J, of this manual.

NOTICE: The air intake pipe must be supported every 4 feet. After making sure the length of the piping is correct, glue all connections in place except the connection to the burner box.

If the combustion air piping is installed in a warm humid place, such as a laundry room or above a suspended ceiling, it must be insulated with a 1.0” foil faced insulation or its equivalent.

If the vent piping is run through an unconditioned space, it must be insulated with a 1.0” foil faced insulation or its equivalent.

: Outside combustion air must not come from an area that is directly adjacent to a pool, hot tub or spa. Measures should be taken to prevent the entry of corrosive chemicals or vapors to the combustion and ventilation air supply. Such chemicals include but are not limited to chlorinated and/or fluorinated hydrocarbons such as found in refrigerants, aerosol propellants, dry cleaning fluids, degreasers and removers. Other harmful compounds may come from bleaches, air fresheners or mastics. Vapors from such products can form acid compounds when burned in a
