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.

IMPORTANT: Model P3DHX12F08001 has an auxiliary limit control that must be in the upper position. Be sure that the auxiliary limit control is above the oil burner assembly.

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 non- combustible 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. Use shims made of noncombustible material.
