The thought of firing it up before installing it has crossed my mind. I should do that.

Thanks.

$100 for propane or $100 for insulation? next refill $100 for propane, insulation is paid for, refill lasts twice as long.

My late brother in law was an HVAC tech and the local college kept trying to get him to teach. One time he installed a large unit in a machine shop and disabled some of the gas jets by tapping them and installing machine screws. this gave a smaller flame and less heat output. You will need to get some one to check that the pilot will still light all the burners. and not make hot spots in the heat exchanger. This modificaation probably will not have UL or your insurance company's approval

I have a gas fired forced air furnace that I heat my garage with when painting.
To control the firing of the burner I put a ball valve between the automatic gas valve and the burner.


Think of it as a gas grille on your patio, the regulator controls the pressure and the valve youturn controls the flow rate.

Works great to control the heat output level.

LEGAL DISCLAIMER:
This modification works well for me but you should not do this modification as it negates any rating or listing that your insurance company may require, and if not done properly may kill you.
