or two 45 degree elbows. Then use a 4" x 3" PVC or 4" x 3" ABS reducing coupling. Then proceed with PVC 4" NON FOAM CORE pipe and fittings for both the intake and exhaust piping. On 4" piping you may go an addi- tional 125 equivalent feet of pipe and fittings, combined total length. The 4" fittings have a friction loss allowance as follows:
4" 90 degree = 3' and a 4" 45 degree = 1'.
The total maximum venting length can be 125', plus the first 10' of each 3", and a maximum fitting allowance of the 3", total two 90 degree or four 45 degree before increasing to 4". Total equivalent would be 30' of 3" plus 125' of 4". Never use different pipe sizes for intake and exhaust.
SPECIAL VENTING INSTRUCTIONS USING 2" VENT PIPE
(ONLY MODELS WITH INPUTS OF 100,000 BTU AND 130,000 BTU ARE CERTIFIED FOR 2" VENTING)
For inlet air supply, top pipe on the right of the shroud, use 2 inch PVC schedule 40. It is very important that you plan the location properly, to eliminate long pipe
runs and excessive fittings. Inlet pipe size must not be reduced. Do not combine the inlet air with any other inlet pipe, including an inlet to an additional similar appliance. The joints must be properly cleaned, primed and cement- ed. The piping must also be properly supported as per local and national standard plumbing codes. It is impor- tant that the piping be clean and free from burs, debris, ragged ends and particles of PVC.
For exhaust piping, lower pipe on the right of the shroud, use 2 inch PVC schedule 40 NON FOAM CORE. Use 2 inch ABS NON FOAM CORE or 2 inch CPVC schedule 40 or 80 only when required to meet local venting codes. Exhaust piping should be sloped back to the connection on the AdvantagePlus, at least 1/4 inch per foot of pipe, to remove the condensate that forms within the pipe. The total combined length of pipe, (inlet air piping plus exhaust piping) including allowances for elbows, should not exceed 85 equivalent feet. The total combined length of pipe, including allowances for elbows, should not be less than 22 equivalent feet (minimum length of 12 feet of piping, including allowances for elbows, on the inlet and the exhaust). Choose your vent termination locations carefully. You must make certain that exhaust gas does not
PIPE / FITTINGS WHEN USING 2" VENT PIPE
All inlet air and exhaust venting may use standard PVC
schedule 40 piping, conforming to ASTM
FOR LONGER VENT LENGTHS WHEN USING 2" VENT PIPE
You may use 3 inch venting on both the intake and exhaust to lower the pressure drop and provide addition- al vent length. It is imperative when using 3 inch venting to follow these instructions carefully. For longer vent lengths, the first 10 feet of both the intake and exhaust piping must be 2 inches. For the first 10 foot use 2 inch PVC schedule 40 NON FOAM CORE, 2 inch ABS NON FOAM CORE or 2 inch CPVC schedule 40 or 80 plus one 90 degree or two 45 degree elbows. Then use a 2" x 3" reducing coupling of like material. Then proceed with 3 inch PVC schedule 40 NON FOAM CORE, 3 inch ABS NON FOAM CORE or 3 inch CPVC schedule 40 or 80 pipe and fittings for both the intake and exhaust piping. On 3 inch pipe you may go an additional 125 equivalent feet of pipe and fittings, combined total length. The total combined equivalent vent length would be 30 equivalent feet of
CLEANER / CEMENT
Cement for all venting must be ALL PURPOSE Cement, and must conform to ASTM

IF YOU HAVE A COMBUSTION ANALYZER, THE FOL- LOWING RATINGS WILL BE VERY HELPFUL IN SET- TING UP YOUR ADVANTAGE PLUS:
FOR NATURAL GAS -
CO2 reading should be between (9 1/2% – 10%) O2 reading should be between (3 1/2% – 4 1/2%) CO reading should be under 10 PPM
FOR PROPANE GAS -
CO2 reading should be between (10 1/2% – 11 1/2%) O2 reading should be between (3 1/2% – 4 1/2%) CO reading should be under 10 PPM
