REMOVE CRATE
1.
Remove all banding and pry off crate sides carefully so as not to damage the water heater.
2.
Carefully roll/lift the water heater from the crate base.
MOVE WATER HEATER TO PERMANENT POSITION by sliding or walking. Place drain pan underneath water heater
INSTALL TEMPERATURE AND PRESSURE RELIEF VALVE (if not already installed).
This water heater must be located in an area where the general public does not have access to set temperatures.
AIR REQUIREMENTS
1. Do not obstruct the flow of ventilating air.
2. For safe operation, adequate air is needed for combustion and ventilation. Sooting may result in serious damage
to the water heater and risk of fire or explosion. It can also create a risk of asphyxiation. Such a condition often will
result in a yellow, luminous burner flame, causing carboning or sooting of the combustion chamber, burner and
flue tubes.
IMPORTANT-The flow of combustion and ventilating air must not be obstructed.
MECHANICAL EXHAUSTING OF ROOM AIR -
water heater and combustion air is drawn from inside the room, sufficient openings for air must be provided in the
walls. UNDERSIZED OPENINGS WILL CAUSE AIR TO BE DRAWN INTO THE ROOM THROUGH THE WATER
HEATER'S VENTING SYSTEM, CAUSING POOR COMBUSTION THAT MAY BE HAZARDOUS TO LIFE.
SOOTING MAY RESULT IN SERIOUS DAMAGE TO THE WATER HEATER AND RISK OF FIRE OR EXPLOSION,
WHICH CAN ALSO CREATE A RISK OF ASPHYXIATION. Refer to local codes and /or National Fuel Gas Code
(ANSI Z223.1-Latest Edition), or in Canada CAN/CGA B149.1 Natural Gas Installation Code (Latest Edition) or
CAN/CGA B149.2 Propane Installation Code (Latest Edition) for proper air opening sizing.
CONFINED SPACES
If the water heater is installed in a confined space (volume is less than 50 ft.
total input rating of all gas appliances in that space), air must be supplied through two permanent openings. One opening
must be within 12 inches (30.5 cm) from the top of the enclosure and one within 12 inches (30.5 cm) of the bottom. The
openings must be protected by metal louvers or 1/4" (6.4 mm) min. mesh metal screen. The size of the openings are as
follows:
The draft diverter relief opening of the water heater and combustion air inlet must be in the same atmospheric
pressure zone. Large exhaust fans in kitchens and other locations can lower the air pressure inside an enclosure and
interfere with the proper operation and venting of the water heater. In these cases, the water heater should be
installed in a separate room with the combustion and ventilation air supplied directly from outdoors as previously
described.
1. If the openings communicate directly with an additional room(s) of sufficient volume, each opening must have a
minimum free area opening of 1 in.
