HORIZONTAL INSTALLATION

WML-C AND MPL-B furnaces models are assembled and shipped ready for installation in the down-flow position. The furnace may be installed in either of the horizontal positions; warm air discharging left or warm air-discharging right by following these steps:

1.Rotate the furnace 90° to the desired position.

2.Remove the three nut and washer sets fastening the oil burner assembly to the furnace. Rotate the oil burner assembly to be in the normal upright position.

3.Re-align the oil burner assembly to the combustion chamber (fire-pot), and then secure into place with the three nut and washer sets.

NON-SUSPENDED INSTALLATION

Maintain clearances to combustibles as outlined in Table 1. Installation on a combustible floor requires a clearance of 1 inch. This can be done by using a noncombustible material such as one- inch thick channel iron or similar material. The furnace must be supported in such a way as to not allow twisting or sagging of the cabinet. Suggestion; as a measure to prevent fuel oil from accumulating in locations other than the fire pot, as could be the case in the event of nozzle drip, install the furnace with an approximate 2-degree slope from the oil burner casing towards the fire pot.
