SECTION 10 GAS CONVERSION INSTRUCTIONS
10.1 Reznor ML series air heaters are designed to operate
on Natural-Propane-Butane gas and will be supplied
as ordered for the gas type specified.
10.2 In the event it is required to convert to a different
gas type to what has been supplied, the conversion
of the gas burner and gas controls is necessary. A
Reznor conversion kit must be used and comprises
the items illustrated in fig.11.
10.3 When converting from natural gas to Propane or
Butane gas the gas regulator on the gas valve
should be adjusted to maximum pressure, i.e.
screwed inwards to stop position, and then sealed
to prevent re-adjustment.
N.B. Normally natural gas air heaters are supplied
without air shutter assemblies. If converting to
from propane or butane to natural gas set air shutter
as below 18.0mm open.
10.4 To carry out the conversion, refer to the appropriate
instructions in section 8, specifically paragraphs 8.5
and 8.6 which explain appropriately the accessibility
and testing requirements.
In addition to changing the gas valve and burner
injectors, it is necessary to reset the burner ribbon
aeration shutter as appropriate & place the
necessary over stickers. Carry out the
commissioning procedure stated in section 7 of this
document when conversion is completed.
