WATER HEATER INSTALLATION
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 53.
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 Exhaust/Condensate
Elbow, see Figure 53.
5. Brace the condensate drain line with oor mounted standoffs
every three feet.
6. Ensure the condensate drains freely during start up, see
Start Up on page 53.
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 ttings (elbows, couplings, and adapters)
necessary to install a condensate drain line between the
Exhaust/Condensate Elbow 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 eld installed condensate drain line must not be less
than 1/2 inch PVC in size.
3. DO NOT remove, modify or alter the factory condensate trap.
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
condensate drain connection on the Exhaust/Condensate Elbow
and a suitable building drain, see Figure 53.
