GAS CONVERSION
 VRA-4E air heaters are designed to operate
on natural or propane gas and will be
supplied fitted for the gas type ordered. In
the event of site conversion to a different gas
type it is necessary to convert the gas burner
and burner controls.
 Affix new data plate and gas type over-
sticker.
 Upon completion of conversion re-commission
the air heater in accordance with section 6 of
this document.
 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 plate
To adapt gas injectors and gas inlet pressures,
we refer to table 2A/2B
.
