Bruce how noise is the heater? Are the flames contained or open to shop air.?
Just fan noise, not loud.
It was a special order to get one smaller than 45,000, not cheap. I think it was around $600 or so.
Beacon Morris Brut 30,000
Forgot to mention that it draws cold air from outside. There is a pipe in a pipe, heat thru the center, air on the outside of the inside of the piping!
I don't see any flames, but I would have to read up on the literature to know how it works.
Says that with a • Combustion Air Inlet Kit (For All Separated Combustion Installations)
And:
DUAL VENTING
Beacon/Morris “BRT” units are agency certified for both standard and separated combustion venting. Units are shipped to accommodate either category I or category III horizontal or vertical venting. With the addition of a Beacon/Morris combustion air inlet kit, the unit can be installed as a separated combustion unit.
