Need to remove a stripped Allen wrench-type plug from the OUT PRESS port on top of gas valve

Need to remove a stripped Allen wrench-type plug from the OUT PRESS port on top of a Robertshaw 720-472 gas valve. There are a couple of threads showing above the flat, horizontal surface of the valve body. I was thinking of trying to grab it with some type of pliers, but the metal seems soft and af...

Re: Correct Size (BTU OUT) For This Home?

Check the duct connections going from one half of the home to the other. Might be losing heat there. Also consider Nordyne's M7 furnace. Rated at 95+ efficiency it's a pretty good unit. I replaced my 25 year old Colemen 7995, a 95,000 BTU pilot model furnace, with Nordyne's largest M7 rated at 72,0...

Re: Correct Size (BTU OUT) For This Home?

I replaced one for a neighbor around here and his double wide is roughly similar to this one. I believe it was a 25kw furnace which puts out around 82,000 btu or more if I remember. They have calculators you can use to convert kW to BTU. But just to give you an idea if it is worth it or not. Our el...

Re: Better to run this new motor on med or lo speed?

Been a mobile/manufactured home service guy for over 30 years, 21 my own business. Furnaces usually use low speed with no A-coil to push the air through. When air conditioning is added we usually have to bump the heat speed up to medium so there is plenty of air flow throughout the home. That reall...

Re: Better to run this new motor on med or lo speed?

I would go with medium for heat and high for the air conditioning. There should be wiring there for you to be able to set medium for heat speed and high for air conditioning speed. Ok Dale, thx much. Please also tell me how you arrived at choosing Med speed for heat in this instance, as I will have...

Re: Better to run this new motor on med or lo speed?

It's a 14 x 70 and is a split system, using same blower for cooling. 3-speed motor with a speed selection terminal block (easy speed changes) in the control panel mounted on front of the blower housing. Not a Presidential model however, with the Auto/On & Heat/Cool rocker switches on this control bo...

Re: Lear-Siegler AGC-80 Type B standing pilot Propane burner

So, if that's the case here, the pilot could be lit like other typical standing pilots? Depressing a control knob or lever in the Pilot position while inserting a "match-stick" flame at the pilot burner outlet? Standard thermocouple on this unit also?
