If heater is connected to propane supply cylinder and it is to be
stored indoors, the connection between the propane cylinder and
the heater must be disconnected and the cylinder removed from
the heater and stored in accordance with standard for the storage
and Handling of liquefied Petroleum Gases, ANsI/NFPA 58 and
CsA B149.1, Natural gas and Propane Installation Code.
Analysis of Combustion Waste Products
The probes which check the composition of combustion waste
products and smoke temperature must be positioned as indicated
in Fig. 2. When these tests have been completed the hole which
was drilled for the probe must be sealed with a material which is
resistant to high temperatures and which ensures that the tube
remains airtight.

Connection to Fuel Supply
To connect the burner to the fuel supply follow the instructions in
the Burner Instruction manual.
The gas burner can use both methane gas or propane. Burners
are predisposed at factory to be used with natural gas. If
propane shall be used, burners shall be adapted according to the
instruction manual of the burner. In case of connection of heater
to natural gas,the installation shall conform with local codes, or, in
the absence of local code, with the National Fuel Gas Code ANsI
Z223.1/NFPA and the Natural Gas and Propane Installation Code,
CsA B149.1.
In case of connection of heater to propane supply cylinder, the
installation shall conform with local codes or, in the absence of
local code, with tyhe standard for the storage and Handling
of liquefied Petroleum Gases, ANsI/FNPA 548 and the Natural
Gas and Propane Installation Code, CsA B149.1. Heater must
be located at least 6 ft in the U.s. or 10 ft in Canada from
any propane gas container. Propane gas cylinder shall be in
compliance with national standards and shall be arranged to
provide for vapor withdrawal from the operating cylinder.
The gas shall be turned off at the propane supply cylinder when
the heater is not in use. Visually inspect hose assembly prior to
each use of the heater. If it is evident there is excessive abrasion
or wear, or the hose is cut, it must be replaced prior to the heater
being put into operation. After installation, proper instruments
or devices shall be used to check and avoid any gas leakage. Gas
leakage testing shall be regularly operated.
Regulation of Combustion - I° Operation
After having checked the hermetic seal and of combustion waste
products line, heater may be operated for the first time.
To perform regulation of combustion correctly, combustion waste
products must be analyzed using appropriate instruments: values
recommended by actual standards must be reached.
The regulation procedure has been on the Burner Instruction
Manual; final values of CO2 shall be correspondent to excess air
factor of 1.2 (12.5 for gas-oil, 9.7% for G20. 9.6% for G25. 11.7%
for G30 and 11.7% for G31) while CO level shall be less than 75
ppm.
