Installing the Water Heater
Installation
●
For vertical terminations, install a condensate
drain and trap as close to the appliance as
possible.
●
Slope the vent in accordance with the vent
manufacturer’s installation instructions.
●
Use only corrosion resistant materials for the
condensate drain lines, such as PVC pipe or plastic
hose.
●
The condensate drain pipe (along its entire
length) must be at least the same diameter as the
drain line (5/8 inch).
●
The end of the condensate drain pipe should be
open. The end should not be under water or any
other substances.
●
To help prevent the condensate from freezing,
run the condensate drain line through an interior
wall or between insulation and an interior wall.
●
The condensate collector should be used for
all combination domestic/hydronic heating
applications.
Guidelines
●
Do not allow condensate to enter the water
heater.
●
Do not connect the condensate drain pipe
directly to the storm sewer.
●
Do not connect the condensate drain line with
the evaporator coil drain of an air conditioner.
●
Do not connect the condensate drain line to the
pressure relief valve or the line of the appliance.
●
Use only venting that is approved and identified
as acceptable for your particular model.
3.6 Connecting the Power Supply
WARNING
Electric Shock Hazard
To prevent serious injury or death:
●
ALWAYS follow all applicable electrical codes
of the local authority having jurisdiction.
●
In the absence of such requirements, follow
the latest edition of the National Electrical
Code (NFPA 70) in the USA or the latest
edition of CSA C22.1 Canadian Electrical Code
Part 1 in Canada.
●
ONLY licensed professionals should connect
the power supply.
When connecting the power supply, follow these
guidelines:
●
Do not connect the electric supply until all
plumbing and gas piping is complete and the
water heater has been filled with water.
●
Do not connect the water heater to a 220-240 V
AC power supply. Doing so will damage the water
heater and void the warranty.
●
Indoor models come with a factory-installed,
3-pronged (grounded) plug. Exterior models
come with 3 exposed power wires (line/neutral/
ground) for direct connection to outdoor-rated
wiring. The water heater can be plugged into any
grounded electrical outlet nearby, as it requires
only 2-4 Amps.
●
Keep power cord free of dust.
●
Do not use a broken or modified power cord.
●
Do not bind, bend or stretch power cords.
●
If local codes require the water heater to be
wired directly, remove and discard the factory-
installed plug. Install a power switch between
the breaker and the water heater to facilitate
end-user maintenance and servicing. Connect
the water heater to a 110-120 V AC at 60 Hz with a
maximum of 4 A rating electrical supply.
●
A junction box is provided underneath the water
heater if a direct electrical connection is required.
