I have a Coleman gas furnace with standing pilot light that I would like to convert to electronic ignition if possible. Model number is: 7655-856. If electronic ignition is not available, is there a high efficiency model that's a direct replacement?

Is this in a mobile home?

Natural gas OR propane?

Yes, it is in a mobile home and natural gas fed.

I don't know of any conversion kits from standing pilot to glow plug for mobile home furnaces. Would look into replacing the whole unit. The new unit will be more efficeint than your existing furnace, but I don't believe they make a mobile home furnace with 90 percent plus efficiency.

I agree with mygirlsdad77. You will be better served by a new high efficiency unit.
