GAS CONVERSION
11.1 LCSA-4 air heaters are designed to
operate on natural, propane or butane

Affix new data plate and gas type over-
sticker.
11.3 Upon completion of conversion re-
commission the air heater in accordance
with section 6 of this document.
11.4 Changes to carry out:
Natural gas: use Honeywell VR4601AB
(PN 03 25136) - set pressure regulator as
per Table 2A
propane: use Honeywell VR4601B
(PN 03 25136B) or VR blocking

To adapt gas injectors and gas inlet pressures,
we refer to table 2A/2B.
