I. CONDENSATE REMOVAL SYSTEM
NOTE:
Check with your local gas company to determine if combustion condensate disposal is permitted in your area. In the state of
Massachusetts, condensate must be neutralized before entering a drain.
This condensing high efficiency water heater has a condensate removal system. Condensate is water vapor derived from combustion
products, similar to an automobile when it is initially started. It is very important that the condensate line is sloped down away from the
heater and to a suitable drain.
If the heater condensate outlet is lower than the drain, you must use a condensate removal pump (kit p/n 554200 available from HTP).
If required by local authorities, a condensate filter of lime crystals, marble, or phosphate chips will neutralize slightly acidic condensate.
This can be installed in the field and purchased from HTP (p/n 7450P-212).

NOTES:
1. Condensate line must be pitched at least ¼” per foot to properly drain. If this cannot be done, or a very long length of condensate hose is used,
increase the condensate line to a minimum of 1” ID and place a tee in the line after the condensate neutralizer to properly reduce vacuum lock in the
drain line.
2. Plastic pipe should be the only material used for condensate line. Steel, brass, copper, and other metals will be subject to corrosion or deterioration.
3. NEVER install condensate lines outside. It is very important that the condensate line is not exposed to freezing temperatures or any type of blockage.
Damages due to frozen or blocked condensate lines ARE NOT covered by warranty.
4. Support of the condensate line may be necessary to avoid blockage of the condensate flow.
PART 6 – WIRING
A. LINE VOLTAGE INPUT
The heater must be wired to a 120 volt circuit by a qualified electrician. It is recommended that the heater be wired on its own circuit to
minimize the possibility of circuit failure due to outside causes. The heater requires a maximum of 8 amps at 120 volts in use.
The condensate line must remain unobstructed. If allowed to freeze in the line or obstructed in any other manner, condensate can exit
from the water heater tee, resulting in potential water damage to property. When installing a condensate pump, select one approved for
use with condensing heaters and furnaces. The condensate pump should have an overflow switch to prevent property damage from
spillage. Condensate from the heater will be slightly acidic (pH from 3.2 to 4.5). Install a neutralizing filter if required by local codes.
To avoid electrical shock, turn off all power to the heater prior to opening an electrical box within the unit. Ensure the power remains off
while any wiring connections are being made. Failure to follow these instructions could result in component or product failure, serious
injury, or death. Such product failure IS NOT covered by warranty.
