Prevent Combustion Air Contamination; Removing A Heater From A Common Vent System - Pioneer PHR100-55 Instruction Manual

Failure to provide an adequate supply of fresh combustion air can cause poisonous flue gases to enter
living space, which could result in severe personal injury or death. NOTE: To prevent combustion air
contamination, see Table 1.
F. PREVENT COMBUSTION AIR CONTAMINATION
Install intake air piping for the heater as described in the Venting Section. Do not terminate exhaust in
locations that can allow contamination of intake air.
Ensure that the intake air will not contain any of the contaminants listed in Table 1. Contaminated air will
damage the heater, resulting in possible substantial property damage, severe personal injury, or death.
For example, do not pipe intake air vent near a swimming pool. Also, avoid areas subject to exhaust
fumes from laundry facilities. These areas always contain contaminants.
NOTE: DAMAGE TO THE HEATER CAUSED BY EXPOSURE TO CORROSIVE VAPORS IS NOT
COVERED BY WARRANTY. (Refer to the limited warranty for complete terms and conditions).
