Yes its ok, just make sure the air pressure pump is dialed in right. With the right air pressure the heater will perform at its best and burn as clean as it can. Its the slotted set screw (plastic usually) on the back next to the air filter. Turn it in 1/4 turn at a time till the nose cone is almost all red or orange in color. This will give you the cleanest burn. Then adjust doors/windows for fresh air as needed. Hope this helps
