• All readings must be made while heater is operating.
• Relying on any reading taken while heater is off may result in
poorperformanceanddifcultyinoperation.
Table 3. Supply Gas Input Pressure Requirements
a
Pull gas inlet grommet away from heater body panel.
b
Remove one screw and the gas valve access panel.
c
Remove 1/8 in NPT plug using a 3/16 in Hex Key.
d
Install a 1/8 in to 1/16 in barbed adapter.
e
Connect positive manometer lead to barbed adapter.
• Inlet gas pressure must be taken while the heater, and
if possible, all other gas burning appliances supplied
by the same gas delivery system, are operating.
• If the gas supply pressure is less than required,
check for an undersized pipe between the meter and
the heater, a restrictive tting, or an undersized gas
meter. If needed contact the local gas utility company
for assistance.
• Once proper inlet pressure has been conrmed, shut
off gas supply.
• Remove manometer, hose and barbed tting
from the gas valve.
• Apply joint compound to the NPT plug and reinstall.
• Before operating the heater, test the gas supply
system and all connections for leaks using a soap
solution. Do not
use an open
ame to test for
leaks.
• Reinstall the
gas valve
access panel.
• Secure the gas
inlet grommet at
heater side panel.
5.3 Special Precautions for LP Gas
Under the same environmental conditions, liquid propane
(LP) gas is more dense or heavier than air and will more
readily collect or pool in enclosed areas if adequate
ventilation is not provided. It is not recommended to
install LP gas heaters in enclosed areas such as pits.
Locate heaters a safe distance from LP gas cylinders and
lling equipment. Consult the National Fuel Gas Code
(NFPA
®
54/ANSI
®
Z223.1, latest edition), the Liqueed
Petroleum Gas Code (NFPA 58, latest edition), the
Natural Gas and Propane Installation Code in Canada
(CAN/CSA B149.1, latest edition), and any other local
codes and re protection authorities about specic
installation restrictions in your area.
For ALL installations the combustion air openings
requirements and NFPA54 / ANSI Z223.1 MUST be
followed for safe and proper operation.
