If the confined space is within a building of tight construction, air for combustion must be obtained from the outdoors as outlined in the
Venting section, Part 5 of this manual.
When drawing combustion air from the outside into the mechanical room, care must be taken to provide adequate freeze protection.
Do not attempt to vent this water heater by any means other than those described in this manual. Doing so will void the warranty, and
may result in severe personal injury or death.
Failure to provide an adequate supply of fresh combustion air can cause poisonous flue gases to enter living space, resulting in severe
personal injury or death.
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 below. Contaminated air will damage the heater, resulting in possible
substantial property damage, severe personal injury, or death. For example, do not pipe intake air near a swimming pool. Also, avoid
areas subject to exhaust fumes from laundry facilities. These areas always contain contaminants.
