2.0 Combustion Test and Adjustments
1. The installer MUST perform a complete com-
bustion check to ensure the following combus-
tion levels in Table 2 are met at high and low
input firing rates and the burner is operating at
optimum conditions.
Table 2: Recommended Propane Combustion Settings
The combustion testing and adjustments
must be performed by a qualified installer,
service agency or the gas supplier. All com-
bustion measurements must be performed
with calibrated equipment to ensure proper
readings and accuracy.
Failure to perform a complete combustion
test at both high and low input rates may
result in incomplete combustion and the pro-
duction of carbon monoxide, which can
result in substantial property damage, seri-
ous injury, or death.
The combustion levels should be measured at
high firing rate. If the combustion levels are
not within the range given in Table 2 for Low
Fire after adjusting High Fire, shut the boiler
down and contact Triangle Tube Technical
Support Department. Failure to comply
with this requirement can result in substan-
tial property damage, serious injury, or
death.
The gas valve outlet pressure is factory set to the
correct value and does not require field adjust-
ment or measurement. Measurement or adjust-
ments could result in damage to the gas valve
and can result in substantial property damage,
serious injury, or death.
