Bard 9043-504 is an OEM natural gas high altitude kit used on Bard gas heat wall mounted units to help keep burner operation and combustion performance in spec when equipment is installed at higher elevations where air density is lower. This kit is typically applied when a unit that is set up for natural gas needs the proper high altitude fuel metering setup for the site altitude so the heater runs cleanly, starts reliably, and avoids nuisance issues tied to over firing or improper flame characteristics. Because high altitude requirements vary by model and elevation range, confirm this part number is listed for your exact Bard unit model and serial range in the correct installation or service literature before ordering.
