Utilities - FULTON VSRT Series Installation And Operation Manual

! WARNING
An exhaust fan may draw products of combustion
into the work environment, creating a possible
hazard to personnel. A spill switch installed in the
stack is highly recommended and is required in some
jurisdictions.
! 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.
Particulate matter like lint, dust or smog or
chemicals (example: perchlorethlylene, halogenated
compounds) in the combustion air supply to the
equipment will cause damage or failure of the
burner and is not covered under warranty. High
risk situations for particulate matter to be in the air
include construction and maintenance activities.
When calculating ventilation requirements, heat
losses from the Fulton equipment (and other
equipment) should be considered.

THE GAS SUPPLY
! WARNING
A qualified installer, service agency or the gas supplier
must perform installation and service on the fuel
delivery system.
Gas piping must be installed in compliance with all
applicable codes.
Adhere to the following for installation:
1. No changes shall be made to the factory fuel
train.
2. The pipe and fittings used must be new and free
of dirt or other deposits.

INSTALLATION - 2
3. The piping must be of the proper size to ensure
adequate gas supply to the gas head assembly
without a pressure loss. Consult your gas
company for specific recommendations.
4. When making gas piping joints, use a sealing
compound resistant to the action of liquefied
petroleum gases. Do not use Teflon tape on gas piping.
5. Piping must be installed such that no piping
stresses are transmitted to the equipment. The
equipment shall not be used as a pipe anchor.
6. Components may have vent connections which
must be vented per local codes.
7. The boiler gas train must be isolated from the gas
supply piping system during any pressure testing
of the system at pressures in excess of 1/2 psig
(13.8 inch w.c.).
8. If the supply pressure will exceed 13.8" w.c.,
incoming gas supply pressure must be regulated
by a non-stacking, tight, shut-off regulator.
Overpressure protection must be provided per
local jurisdictional requirements.
9. After gas piping is completed and before wiring
installation is started, carefully check all piping
connections (factory and field) for gas leaks. Use
a soap and water solution.
10. All gas piping must be arranged 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.
! WARNING
Do not use matches, candles, flame or other sources of
ignition to check for gas leaks.
The vent line connection on the gas pressure regulator
must be piped to outdoor air by the installer in
accordance with National Fuel Gas Code, ANSI
Z223-1-1991 or latest addenda. In Canada, gas
installations must be in accordance with the current
CAN/CGA B149.1 and 2 and/or local codes.
! CAUTION
Some soap used for leak testing is corrosive to certain
types of metals. Clean all piping thoroughly after
completing the leak check.
