INSTALLATION
2-7
5. Ensure no piping stresses are transmitted to the equipment. The
equipment shall not be used as a pipe anchor.
6. Ensure all vent connections on diaphragms, gas valves, pressure
regulators, and pressure switches (gas-fi red units) are vented per local
code.
7. On gas-fi red units with NFPA 85 valve trains, ensure the vent valve is
piped to atmosphere per local code.
8. During any pressure testing of the system at pressures in excess of 1/2
psig (14 inch W.C.), isolate the boiler with the manual shutoff valve
(located at the end of the supplied gas train) from the gas supply
piping system.
9. Ensure the supply pressure is regulated by a non-stacking, tight, shut-
off regulator.
10. Arrange gas piping so that it does not interfere with any cover or
burner, inhibit service or maintenance, or prevent access between
unit and walls or another unit.
11. After gas piping is completed and before wiring installation is started,
carefully check all piping connections, (factory and fi eld), for gas
leaks. Use an appropriate leak test solution.
The Oil Supply
Adhere to the following for installation:
1. Fuel pipes must be of approved materials and of a diameter suitable
for the quantity of oil being delivered to the burner. Vacuum must
not exceed 10 in. (254 mm) of mercury at the pump inlet. Maximum
inlet pressure to oil pump is 3 PSIG.
2. Make fuel connection in accordance with the details on the enclosed
fuel pump cut sheet.
3. Ensure fuel oil piping is in accordance with local/national
requirements.
4. Meet the maximum pressure allowed at the fuel oil pump inlet per
the National Fire Protection Association (NFPA).
5. Oil pumps are of a two-line design system, requiring a return line and
a supply line. The oil pump is factory set per Test Fire Shee t. Do not
alter the setting without consulting the factory.
6. A stop valve, a check valve, and an oil fi lter must be installed on the
oil supply line.
7. Ensure there are no loose fi ttings. Loose fi ttings in the fuel oil line will
permit air to enter the fuel line and cause improper fi ring.

WARNING
A qualifi ed installer, service agency or the
gas supplier must perform installation and
service on the fuel delivery system.
Do not use matches, candles, fl ame or
other sources of ignition to check for gas
leaks.
What to do if you smell gas:
Do not try to light the appliance.
Do not touch any electrical switch.
Do not use any phone in the building.
Leave building and contact gas supplier
from neighbor’s phone. If you cannot
reach gas supplier, phone the fi re
department.
When making gas piping joints, maintain
proper ventilation to reduce breathing
hazards.
An exhaust fan may draw products of
combustion into the work environment
creating a possible hazard to personnel.
Ð
CAUTION
It is essential that only fresh air be allowed
to enter the combustion air system. Foreign
substances, such as combustible volatiles
and lint in the combustion system can create
hazardous conditions. If foreign substances
can enter the air stream, the combustion air
inlet must be piped to an outside location.
Failure to do so will void the warranty.
To avoid failures due to poor combustion,
ensure make-up air system is properly
designed.
