How long should I wait before trying again if the pilot doesn't catch on the first try?
Wait a full five minutes with the knob at OFF before trying again. That pause lets any unburned gas clear out of the firebox and vent, so you're never lighting into an accumulated pocket. If you smell gas at any point, stop, leave the house, and call us from outside — don't keep trying to light it.
Why five minutes, not thirty seconds
The wait is about clearing unburned gas, not patience for its own sake. When a pilot fails to catch, a little raw gas has already entered the firebox. In a sealed direct-vent unit especially, that gas doesn't just vanish — it needs time to dissipate before you introduce another spark or flame. Five minutes with the knob at OFF is the standard printed on virtually every unit's label, and it's there so you're never lighting into an accumulated pocket. Propane behaves a bit differently than natural gas out here — it's heavier than air and settles low, which is one more reason the pause matters in Fairview and Candler cabin country. Rushing it is the one shortcut worth never taking.
If it fails two or three times in a row
Stop cycling it. A pilot that won't catch after a few honest tries is telling you something, and it usually isn't your technique. The classic WNC cause is a pilot orifice clogged with spider webbing and dust after sitting all summer — we get a wave of these calls the first cold week every fall. It can also be a weak thermocouple or, if your propane tank recently ran dry or the gas was off for service, simply air in the line that needs purging. Repeated no-catch is a service call, not a persistence contest.
The one rule that overrides everything
If you smell gas at any point — during the wait, between tries, anytime — don't try again. Leave the house and call us from outside at (828) 545-0525. A faint whiff that clears is one thing; a persistent gas smell is a stop-everything situation. Otherwise, cleaning a clogged pilot or purging a line is quick, inexpensive work, and most of these we fix in a single visit with parts already on the truck.
