Relief Valve Requirements (T&P)

All water heaters must be fitted with a proper temperature
and pressure relief valve. These valves must be certified as
meeting the requirements of the “

Standard For Relief

Valves For Hot Water Supply Systems, ANSI Z21.22/CSA
4.4”

.

If this water heater has been exposed to flooding, freezing,
fire or any unusual condition, do not put it into operation until
it has been inspected and approved by a qualified service
technician.

THESE CONDITIONS CAN RESULT IN UNSEEN INTER-
NAL DAMAGE

and are not subject to warranty coverage.

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.

Fuel Specifications

All JOHN WOOD brand water heaters are designed to burn
only fuels not heavier than No.2 (furnace) oil.

III) INSTALLATION

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
the place of purchase for further instructions.

After installation, dispose of packaging material in the
proper manner.

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.

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.
