Wall-furnace replacements in Newark

Two old heaters, two separate problems

The hallway wall heater had no heat. On the first visit we fixed an electrical problem and relit its pilot, but both heaters were old and in poor condition. The second heater had a separate fault. We removed both and installed two Williams gas wall furnaces, with replacement wall thermostats.

A Williams Monterey and its connections

This installation used a Williams Monterey 25,000 BTU top-vent natural-gas wall furnace. Along with the heater, we installed a new gas shutoff valve, refitted the vent connector and calibrated the thermostat controls. The published photo record shows the installed furnace and the work around it.

Replacement equipment and plan submittals

Newark issues permits electronically. Its Building Inspection Division lists replacement HVAC equipment in existing locations among the residential applications that may not require plans. It provides separate application routes for work requiring plans and work without plans; the exception concerns drawings, not a waiver of the permit.
