as a Category I, non-direct
vented water heater which takes its
combus on air either from the installa-
on area or from air ducted to the unit
from the outside. This water heater
must be installed according to all local
and state codes or, in the absence of
local and state codes, the “Na onal
Fuel Gas Code”, ANSI Z223.1(NFPA
54)-current edi on. This is available
from the following:

Before you start, be sure you
have the following tools and
supplies:
• Common plumbing tools (depend-
ing on what type of water pipes
you have).
• Te fl on® tape or pipe joint com-
pound approved for potable water.
• For homes with copper pipes, you
may purchase a Gas Water Heater
Hook-Up Kit (available at your local
plumbing supplier ) with compres-
sion
fi ngs that don’t require
soldering. This kit includes two 12”
fl ex water lines, two compression
fi ngs, an 18” fl exible gas line, two
nipples, and Te fl on® tape.
• For homes with plas c pipe, use
threaded connectors suitable for
the speci
fi c type of plas c pipe
used: CPVC or PEX (cross-linked
polyethylene). Do not use PVC
pipe.
• Non-corrosive gas leak detec on
solu on made from hand dish-
washing soap mixed with water (1
part soap to 15 parts water) or chil-
dren’s soap bubbles and a small,
so -bristled brush.
• An appliance dolly or hand truck to
move the water heater.
Recommended Accessories:
• A metal drain pan.
• Automa c water leak detec on
and shut-o
ff device.
• Pressure Reducing Valve.
• Thermal Expansion Tank.
• Thermosta c Mixing Valves at each
point-of-use.
• Fuel gas and carbon monoxide
detector.
Combus on and
Ven la on Air Supply
Before installing the water heater, you
must determine the amount of air
needed to supply this water heater
and any other gas appliances in the
same area and provide adequate air for
combus on and ven la on. Consult a
quali
fi ed person if you’re unsure of the
proper way to supply air to your water
heater.
WARNING! This gas water heater
requires an adequate source of clean
air for combus on and ven la on.
Without su
ffi cient air, your water
heater will have frequent pilot outages
and may emit excessive and abnormal
amounts of carbon monoxide.
Before beginning:
Calculate total BTU/HR ra ng of all ap-
pliances.
To calculate the combus on air and
ven la on required, add up the total
BTU/HR ra ngs of all gas burning ap-
pliances (e.g., water heaters, furnaces,
clothes dryers) in the same area.
Your water heater’s BTU/HR ra ng is on
the data plate, located next to the gas
control valve/thermostat. The BTU/HR
ra ngs should be on the other appli-
ances’ data plates. If you have trouble
determining the BTU/HR ra ngs,
contact the manufacturer or have a
quali
fi ed person determine the ven la-
on requirements. NOTICE: If you are
replacing your old water heater with
one that has a higher BTU/HR ra ng,
the amount of ven la on required may
be greater.
