This product contains fiberglass wool and ceramic fiber
materials. Airborne fibers from these materials have been
listed by the State of California as a possible cause of can-
cer through inhalation. Use special care when handling
ceramic fiber (chamber lining and base insulation) materials.
Ceramic fibers can be converted to chrystobalites, a sub-
stance listed as a probable cause of cancer. Suppliers of
fiberglass wool products recommend the following mea-
sures be taken when handling these materials:
Precautionary measures:
• Avoid breathing fiberglass dust.
• Avoid contact with skin and eyes.
• Use a National Institute for Occupational Safety and
Health (NIOSH) approved dust/mist respirator.
• Wear long-sleeved, loose fitting clothing, gloves and eye
protection.
• Wash work clothes separately from other clothing. Rinse
washer thoroughly.
Removing the burner may generate airborne fiber concen-
tration requiring additional protection.
First aid measures:
• Eye contact - Flush eyes with sterile water to remove for-
eign objects. If irritation or other symptoms persist, seek
medical attention.
• Skin contact - Wash affected areas gently with soap and
warm water after handling.

Unpacking the Water Heater
Important: Do not remove any permanent instructions,
labels, or the data label from outside of the water heater or
on the inside of panels.
• Remove exterior packaging and place installation com-
ponents aside.
• Inspect all parts for damage prior to installation and
start-up.
• Completely read all instructions before attempting to
assemble and install this product.
If you observe damage to the water heater or any of its com-
ponents, DO NOT ASSEMBLE OR INSTALL IT OR MAKE
ANY ATTEMPT TO FIX THE DAMAGED PART(S). Contact

Location Requirements
The water heater must be installed indoors in an area not
subject to freezing temperatures and in a vertical position on
a level surface. Water heaters located in unconditioned
spaces (e.g., attics, basements etc.) may require insulation
of the water piping, drain piping and venting to protect
against condensation.
The water heater must be installed on a non-combustible
floor, as close to the chimney as practical. Select a location
as centralized within the piping system as possible. The
heater should be located in an area where leakage of the
tank or connections will not result in damage to the area
adjacent to the water heater or to lower floors of the struc-
ture (see “IMPORTANT” notice on the following page).
Before installing this water heater, consideration and plan-
ning must be given to the following details:
• Proximity to walls and other objects (see Figures 1, 2 &
3).
• Access to oil supply (see “Oil Supply”).
• Routing and support of the vent piping and termination
(see “Venting”).
• Position of water supply and placement of water piping
and floor drain (see “Water Supply”).
• How and where to obtain combustion and ventilation air
supply. (see “Air Requirements”).
• Connection to the electrical service. (see “Electrical
Supply”).
CAUTION:
Possible cancer hazard by inhalation. Can
cause respiratory, skin and eye irritation.
WARNING
• Do not use gasoline, crank case oil or an
oil containing gasoline.
• Do not tamper with unit or controls.
• Do not leave paper or rags around the
burner or heater.
• Do not experiment with the burner.
CAUTION
Hydrogen gas can be produced in a hot water system
served by this heater that has not been used for a long
period of time (generally two (2) weeks or more).
Hydrogen gas is extremely flammable and can ignite
when exposed to a spark or flame. To reduce the risk of
injury under these conditions, it is recommended that the
hot water faucet be opened for several minutes at the
kitchen sink before using any electrical appliance con-
nected to the hot water system. Use caution in opening
faucets. If hydrogen is present, there will probably be an
unusual sound such as air escaping through the pipe as
the water begins to flow. There should be no smoking or
open flame near the faucet at the time it is open.
III) INSTALLATION
WARNING
Excessive Weight Hazard
Use two or more people to move and install
water heater. Failure to do so can result in
back or other injury.
