Failure to properly vent the water heater to the outdoors as out-
lined above and in the following section can result in unsafe opera-
tion of the water heater causing bodily injury, explosion, fire or
death.
NOTICE: DO NOT use in conjunction with a GFCI. To
avoid the risk of fire, explosion or asphyxiation from carbon
monoxide, NEVER operate this water heater unless it is properly
vented and has an adequate air supply for proper operation. It
is important that the vent pipe engages fully into any pipe fitting
and be kept in that position until the adhesive has fully cured.
DO NOT drill or punch holes in the plastic pipe or fittings.
