should have a free area of one square inch per 1,000 Btu/hr (22cm 2 /kW) of the total input of all appliances in the space, but not less
than 100 square inches (645cm
2
).
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 6 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 appliance 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, which could result
in severe personal injury or death.
F. PREVENT COMBUSTION AIR CONTAMINATION
Install intake piping for the appliance as described in the Venting section. Do not terminate exhaust in locations that can allow
contamination of intake air.
You must pipe outside air to the appliance air intake. Ensure that the intake air will not contain any of the contaminants below.
Contaminated air will damage the appliance, resulting in possible substantial property damage, severe personal injury, or death. For
example, do not pipe intake near a swimming pool. Also, avoid areas subject to exhaust fumes from laundry facilities. These areas
always contain contaminants.
