No, the furnace can only be lit automatically by its hot surface ignition system to avoid potential shock hazards.
What should I do if the orifice hole appears damaged?
If the orifice hole appears damaged or it is suspected to have been redrilled, check the orifice hole with a numbered drill bit of the correct size. Never redrill an orifice to ensure proper flame characteristics.
How can I verify the natural gas input rate?
To verify the natural gas input rate, turn off all other gas appliances and pilots, run the furnace for a minimum of 3 minutes in heating operation, then measure the time in seconds for the gas meter to complete 1 revolution and refer to Table 14 for cubic feet of gas per hour.
