I have an Empire 15,000 BTU direct vent heater. The gasket at the inspection
window lasts only a short time and then fumes are vented to the room instead
of outside. Would furnace cement work just as well? How difficult would it
be to get it apart if the pilot needed to be relighted? The heater has one
of those piezo ignitors but due to faulty design or manufacture, it never
worked so the inspection window must be opened to relight the pilot with a
match. Is there a longer lasting material that I could cut for a gasket?
I'm using the gasket supplied by Empire, their part number 712098. The local
serviceman who is an Empire dealer said, "Oh those things don't last" and he
threw it away. I asked him if it would be ok without the gasket and he said
yes, but of course, it isn't ok because it leaves a space of about 1/16 of
an inch between the inspection window and the firebox.
I've not seen what you have so I can't give a perfect answer, but there are
many types of insulation that may work. For wood burning stoves there is a
braided rope that fits in a groove. For boilers and heaters there is stuff
on a roll, about 1 inch wide that you can configure as needed. Worth
Thanks for the suggestion. I'll check on it at the hardware store tomorrow.
Here's a link to the gasket:
No service people in this area qualified to do that. I've had three
different propane service companies here in two years and finally had to
hire a plumber to come in and redo the gas lines because none of the gas
people knew how to run gas lines correctly. This morning I e-mailed another
Empire dealer in a city near here asking if they had the gasket. No reply.
Rural southeast part of the country, maybe 6th grade education? Maybe the
guy who can read wasn't in today.
The only thing the hardware store has is high temperature gasket material
for automotive use such as oil pan gasket. Do you think it'll work on a
furnace firebox? Lacking a thermocouple I can't tell how hot the firebox
gets at that point.
