Ornamental gas log fireplace

Joe_10 Member Posts: 22
Got a job where HO is installing a direct vent ornamental fireplace (that means I have discovered that there is no eff. rating or net output.) With an input rating of 23500btuh. I talked to the supplier who said maybe 50% output for heat only radiation would be through the glass front. GC wants to reduce HBB amount in room to reflect input from gas fireplace. The heat loss for the room is 16500btuh at an outdoor design temp of 5*. Altitude is 7100ft. I am wondering if expectinng 50% from that fireplace is reasonable. What input if any would you use with in this situation. The room as in one friends terms is antisolar. North side of house and well shaded.

    gas fireplace

    Is ornamental and just that.

    I would never include that in the heat loss of the room. Are they going to turn that on at six in the morning ?

    Is that going to be running Jan 18th when its ten below zero and the customer is out to dinner. Can you say Freeze up ?

    Just my opinion.

    Unless it's \"Heater Rated\"

    it can't be on a thermostat unless it's heater rated, needs to be a wall switch or remote, either way I would ignore it for heat loss since a person should be present when it's in use.

    I have to agree with scott

    ornamental is just that. your lucky it is direct vent with glass doors or you would be ADDING hwbb to compensate for it. We hade one job where the fireplace didn't have glass doors and it was standing pilot, and the installer fixed the fireplace damper permanantly open so as to avoid liabilty, and you can guess how well that room heated when the fire was out.
