COndEnsAtE dRAIn InstALLAtIOn
Installation must conform with these instructions and local
building codes.
Field supplied materials required for installation include:
• Approved PVC cement and PVC primer.
• 1/2 inch PVC pipe - minimum length to equal the distance
between the water heater and a suitable building drain.
• 1/2 inch PVC fittings (elbows and couplings) necessary to
install a condensate drain line between the Condensate
Drain Trap Assembly and a suitable building drain.
• Floor mounted standoffs to brace the drain line.
InstALLAtIOn nOtEs
1. The condensate drains from the water heater's covered by
this instruction have PH levels between 4.3 and 5.0. Install
a commercially available neutralizing kit if required by local
codes. lower PH levels are acidic. Do not connect a metal
condensate drain line, such as copper pipe, to the water
heater for this reason.
2. The field installed condensate drain line must not be less

InstALLAtIOn InstRuCtIOns
1. ensure the water heater's on/off switch is in the "off" position.
2. Install a 1/2 inch PVC condensate drain line between the
condensate drain connection on the Condensate Drain Trap
and a suitable building drain, see Figure 46 and Figure 47.
3. Terminate the condensate drain piping with an elbow above
the drain. ensure that any discharge will exit the condensate
drain line no more than 6 inches (15.2 cm) above a suitable
building drain, or external to the building, see Figure 46.
nOtE: In cold climates it is recommended the condensate
drain be terminated at a suitable drain inside the building.
4. ensure the condensate drain line is not elevated above the
condensate drain connection on the trap, see Figure 47.
5. brace the condensate drain line with floor mounted standoffs
every three feet.
6. ensure the condensate drains freely during start up, see
Start up on page 50.
