Conversions - ECR International G95V Installation Manual And Operating Instructions

GAS INLET PRESSURE
The natural gas inlet supply pressure should be 5"
to 7" w.c. (7" w.c. recommended). The LP gas inlet
supply pressure should be 11" to 14" w.c. (12" w.c.
recommended). These pressures must be main-
tained while all other gas fired appliances are oper-
ating at maximum conditions.
IMPORTANT: Do not exceed 14" w.c. inlet pres-
sure with either fuel.
The gas valve has two adjustable internal
regulators for controlling burner manifold pressure.
Burner manifold high fire and low fire pressures are
listed on the furnace rating plate.
LEAK TESTING
All new gas piping installations should be pressure
tested as specified by CAN/CGA-B149.1 & 2, or
NFPA 54 ANSI Z223.1 or ANSI/NFPA 58, "Standard
for the Storage and Handling of Liquefied Petro-
leum Gases."
HIGH ALTITUDE: In Canada, the furnace may be
converted for high altitude (2000-4500 feet) by
changing the burner orifices. The Conversion Kit
part number 550001641 contains both natural gas
and LP gas orifices. (Table 7)
In the United States, the modifications for high alti-
tude are based on a 4% reduction of input capac-
ity for every 1000 feet above 2000 feet above sea
level. Table 6 (next page) illustrates the impact of
altitude for selected elevations. Consult with local
fuel suppliers or authorities to determine local regu-
lations or customs.
NATURAL TO LP GAS: This series furnace is manu-
factured as a natural gas (sea level) appliance that
may be converted to LP gas through use of the Con-
version Kit part number 550001648. This kit con-
tains the orifices needed for all models, the regulator
springs for the gas valve, and a label to affix adja-
cent to the appliance rating plate to alert subsequent
service technicians of the conversion.
Gas piping that has not been pressure tested, from
the manual shut-off valve to the furnace gas valve
for example, should be leak tested using an elec-
tronic combustible gas detector, a commercially
prepared leak detector, or other locally approved
method. A leak detector solution can be prepared
by mixing a small quantity of dish detergent with
water and daubing it onto the gas piping, especially
the joints.
NEVER PURGE A GAS LINE INTO THE COM-
BUSTION CHAMBER.
NEVER USE A MATCH, TAPER, CIGARETTE
LIGHTER, FLAME OR ANY OTHER IGNITION
SOURCE TO CHECK FOR LEAKS IN A GAS
LINE.
FAILURE TO ADHERE TO THIS WARNING
CAN CAUSE A FIRE OR EXPLOSION RE-
SULTING IN PROPERTY DAMAGE, PERSON-
AL INJURY, OR LOSS OF LIFE.

15 - CONVERSIONS

LP TO NATURAL GAS: Although the furnace is
manufactured initially as a natural gas appliance, if,
after an LP gas conversion it becomes necessary
to convert back to natural gas and the original parts
are unavailable, The Conversion Kit part number
550001816 may be obtained.
