(d) Remove exhaust cover and place exhaust stack over exhaust pipe. If additional
exhaust pipe is desired, use same size of pipe as used on the heater or larger.
NEVER REDUCE PIPE SIZE. Limit length of exhaust pipe to 20 feet. Longer
pipe runs may cause condensation of exhaust gases and other complications. All
pipe joints must be tight. Pitch any connecting stack or pipe upward at least one foot elevation
for every ten foot run.
! WARNING !
If heater is operated inside a building, the exhaust gases will be conducted to the outside by means of an
extension pipe. Failure to comply may result in death or serious illness.
(e) Remove air outlet cover and attach flexible ducts. A 12 inch flexible duct can be
attach directly to the duct connector at heat exchanger air outlet (see figure 4-6).
For 6 inch flexible ducts, install a 6 to 12 duct adaptor on duct connector, or
at the end of a 12 inch duct.
NOTE
Kinks in the air ducts impede air flow. Spread out ducts so as to avoid sharp bends or kinks.
