SAFETY PRECAUTIONS
FOR YOUR SAFETY, THE FOLLOWING SAFETY PRECAUTIONS SHOULD
BE FOLLOWED AND ENFORCED.
IF YOU SMELL GAS:
•OPEN WINDOWS
•DON’T TOUCH ELECTRICAL SWITCHES
•EXTINGUISH OPEN FLAMES
•IMMEDIATELY CALL YOUR GAS SUPPLIER
1. Instructions must be posted in a prominent location and all safety
precautions taken in the event the user smells gas. Obtain this
information from your local gas supplier.
2. LIGHTING: Follow the instruction on page 6 and label attached to
right side of water boiler.
3. Do not place anything over the flue opening.
4. Do not place combustibles or non-combustible materials in the
proximity of water boiler as this could cause fires or obstruct air flow
to the main burners.
5. This installation must conform with local codes, or in absence of local
codes with the National Fuel Gas Code ANSI Z223.1, latest edition.
6. Provide adequate air supply and ventilation.
7. Provide adequate clearance for air openings into the combustion
chamber.
8. Provide clearance for servicing and proper operation. Minimum
clearance from combustible construction 8” from back and 6” from
side.
9. Boiler must be disconnected from gas supply during any pressure
testing of pipelines in excess of ½ psig, and isolated (by turning off
gas shut-off valve) during any testing less than ½ psig.
10. Retain this manual for future reference.
UNPACKING INSTRUCTION: Carefully unpack the water boiler and
inspect immediately for shipping damages. Your automatic water boiler
was shipped in a carton designed to give maximum protection in normal
handling. It was thoroughly inspected before leaving the factory and the
carrier accepted and signed for it. File any claims for shipping damage or
irregularities with the carrier.
ASSEMBLY: The four legs, faucet, float ball, and vent cap drain are
packed separately with the water boiler. Install legs by tilting the water
boiler on its side and screwing the legs into the leg supports until hand
tight. Carefully right the unit and install it in its permanent location,
being sure to leave at least 6” on the right side of the water boiler for
access to the control box. Level the unit by adjusting the bottom pad of
the legs. Screw the ball float (54 on Parts Ill.) onto the end of the water
inlet valve rod (53). Place the vent cap (50) into the recess in the top of
the unit. Mount the faucet assembly (56) onto the shank (18).

INSTALLATION AND OPERATING INSTRUCTION:
PRE-INSTALLATION INSTRUCTIONS: The installation of your water boiler
must be made by a licensed plumber and the installation must conform
with State and Local Codes or in absence of Local Codes, with the
National Fuel Gas Code ANSI Z223.1 a latest version.
AIR SUPPLY AND VENTILATION: Adequate ventilation and air supply
must be provided in order for the water boiler to operate properly and
efficiently. The area in front of and above the unit must be clear to avoid
any obstruction of flow of combustion and ventilation air. DO NOT under
any circumstances, connect the water boiler flue directly to a building
exhaust system or place the flue outlet directly into the plenum of the
exhaust hood as it will adversely affect the gas combustion of the water
boiler.

CLEARANCES: Your water boiler is design certified to use on combustible
floors. The side and back clearances for combustible constructions are as
follows: 6 inches from side and 8 inches from back. The water boiler
must be installed with 4 inch high legs provided.
GAS CONNECTION: Before connecting the water boiler to the gas line,
check the rating label on the side panel to make sure that the gas type
called for on the label coincides with the type of gas available on site. A
3/8 NPT gas connection is needed to connect the unit to the gas line. An
accessible manual shut-off valve must be installed in the gas supply line
in case of an emergency. The gas supply pipe must be sized to
accommodate all the gas fired equipment that may be connected to it.
Check with your local Gas Company as to proper pipe size. Sealant on all
pipe joints must be resistive to propane gas. Before attempting to light
the water boiler, check all joints for gas tightness using a soap and water
solution.
WATER CONNECTION: Use ¼ inch outside diameter copper tubing to
connect the unit to the water supply line. The water line must have a
shut-off valve (supplied by a plumber). At the unit, connect the tubing to
the compression water inlet valve at the upper right hand side of the
unit.
NOTE: Connecting the unit to a warm water supply will speed by heating
and recovery time.
PRIMING OR INITIAL FILLING: Turn on the water supply. The unit fills at
the rate of 1 gallon/minute. When the water level becomes visible in the
side gauge turn the thermostat knob to ON position. The boiler will now
automatically fill to capacity and heat the water.
LIGHTING AND ADJUSTMENT: Water must be visible in the sight glass
before lighting to pilot. Turn the thermostat knob to its lowest position.
Turn gas cock dial to PILOT position. Depress gas cock dial and light pilot
with a long lighted match through the opening located to the right of the
thermostat. Hold in depressed position for approximately 30 sec. or until
pilot remains lit when dial is released.
NOTE: On the first lighting it may be necessary to hold the dial for a
longer period to allow trapped air to escape from the line.
DIAL SETTINGS AND CORRESPONDING WATER TEMPERATURES:
“1”= 50F, “10”=198F
RELIGHTING: Shut off all gas and wait approximately 3 minutes before
relighting the pilot.

7
SHUTTING DOWN: For temporary shut down, turn the thermostat to
lowest or OFF position; then turn gas cock dial to PILOT position. To shut
boiler down completely, partially depress and turn gas cock dial to OFF
position.
MAINTENACE OR REPAIR: The owner should contact either the
manufacturer or an approved local service company for maintenance or
repair of the unit.
CLEANING: The outside of the unit should be cleaned on a regular basis
using a soap solution and a soft cloth or sponge. Abrasive cleaners are
not recommended. For cleaning the burner see section on removal and
cleaning.
FOR QUALIFIED SERVICE PERSONNEL ONLY
THERMOSTAT CALIBRATION: Turn the thermostat knob to “10” and
remove knob without moving the thermostat shaft. Place narrow bladed
screw driver (1/8”) into the hollow thermostat shaft and engage center
adjustment screw. When thermometer reading approaches 198F slowly
turn the adjustment screw clockwise until the burner goes out. Turning
the screw counter-clockwise will increase the temperature.
SAFETY PILOT: Remove pilot adjustment cap on the gas valve and turn
adjustment screw to provide properly sized flame (3/4 inch long).
Replace the cap.
BURNER: Burners are factory set for maximum performance. Should
further adjustment be required loosen slotted hex screw on side of
venturi and rotate air shutter until flame with soft blue inner cone is
obtained.

BURNER REMOVAL: The burner can be removed with the unit standing in
operating position. Turn off the gas flow to the unit. Allow the burner to
cool off. Remove the wing nut holding the burner to the frame. Pull down
the free burner end, enough to clear the threaded stud and pull the
burner horizontally away from the manifold orifice. The burner can now
be cleaned or replaced. To reinstall reverse the above procedure.
BURNER MAINTENANCE: The burner should be cleaned both inside the
venturi portion and on the outside using a soft bristle brush. The burner
must be replaced into the same position as prior to removal. Once a year
a qualified service agency should be contacted to inspect the appliance
for safe and proper operation.
