WHEN THE UNIT IS RECEIVED, IMMEDIATELY INSPECT IT FOR EXTERNAL OR INTERNAL
DAMAGE. REPORT ANY DAMAGE TO THE FREIGHT CARRIER.
After inspection, keep the unit in its shipping container until it is installed. It can be
installed on combustible and non-combustible floors. Minimum clearances are:
Right Side
2 inches
Left Side
4 inches
Rear
6 inches
In order to service the unit properly, access with at least 24 inches clearance is
needed on the right side.
Install the unit in a well-vented room so that there is an adequate air supply. Since
products of combustion come out of its flue, the appliance must be located under a
ventilation hood.
Do not directly vent the flue.
Level the unit front to rear and left to right by adjusting its legs. Levelness may be
checked by using a spirit level on top of the cabinet.
A free flow of air around the boiler promotes efficient operation. Items which might
restrict air flow must be removed. After installation, do not obstruct the flue, or any
front, side, rear or top vents. Similarly, keep the area directly around the appliance
clear of combustible material.
Installation must conform with local codes, or in the absence of local codes, with the
National Fuel Gas Code, ANSI Z223.1 (latest edition, including the following paragraph:
“The unit and its individual shut-off valve must be
disconnected
from the gas supply
piping system during any pressure testing of that system at test pressures in excess
of 1⁄2 PSI (3.45 kPA). The unit must be
isolated
from the gas piping system by closing
its individual manual shut-off valve during any pressure testing of the gas supply
piping system at test pressures
equal to or less than
1⁄2 PSI (3.45 kPA).”
1. Gas Supply Connection
a.
Connection to the gas supply can be completed with 1/2” NPT pipe
or approved equivalent. Although this is the diameter for immediate
connection to the unit,
gas supply piping must be large enough to
provide volumes and pressure sufficient for 200,000 BTU per hour.
Supply pressure must be at least 5.0” W.C. (14.0” W.C. maximum) for
natural gas or 11.0 W.C. (14.0” W.C. maximum) for propane.
b.
In Canada, the installation must conform to the Canada Gas Code, CAN
1-B149 (Installation Codes for Gas Burning Appliances and Equipment),
and/or local codes.
c.
After the unit has been connected to the gas supply, check piping joints
for leaks. Do NOT use flame to check for leaks. A thick soap solution or
other suitable leak detector should be used.
2. Electrical Supply Connection
a.
The maximum electrical load is 4 AMP. You must provide 115 Volt
Alternating Current, 60 Hz, 1PH, 15 AMP service. Local codes and/or the
National Electrical Code should be followed (ANSI/NFPA-70-1987 - or
latest edition).
AN ELECTRICAL GROUND IS REQUIRED.
WARNING
MAKING ANY ELECTRICAL OR MECHANICAL
CHANGE IN THE UNIT WITHOUT PRIOR
GROEN APPROVAL WILL VOID ALL
WARRANTIES.
