All gas fired heat exchangers are completely
tested at the factory before shipment. This
will remove nearly all of the oils that have
been used in the manufacturing process.
However, trace amounts may remain. When
performing the initial startup at the jobsite, it
is highly recommended that people or any
other living animals, which may be sensitive
to the residual odors or gases, NOT be
present in the conditioned space during the
startup. In all cases, including the initial
factory firing and testing, any of the gases
will be under the acceptable level of
concentration for human occupancy.
Input
The correct heat capacity of the furnace is
controlled by the burner orifices and the gas
manifold pressure. The manifold pressure is
factory set but should be checked at the time
of start-up.
Those sensitive to odors or gases
from trace amounts of residual oils
should NOT be present in the
conditioned space during the startup
of a gas fired installation.
Gas pressure to appliance controls
must never exceed 14”wc (1/2 psi)
1. When pressure testing at 1/2 psi or
less, close the manual shutoff valve
on the appliance before testing.
2. When pressure testing gas supply
line at 1/2 psi or higher, close manual
gas valve and disconnect heater from
supply line to be tested. Cap or plug
the supply line.
Some soaps used for leak detection
can be corrosive to certain metals.
Rinse piping thoroughly after leak test
has been completed.
