Check that floor registers are not covered/blocked by slide outs etc......proper air flow is critical to safe furnace operation.
Also check that return air to furnace is not blocked/obstructed
Otherwise......safe to run furnace (actually safe even if above 2 conditions exist cause furnace hi limit will shut down furnace if it should overheat due to lack of proper air flow)
