Disclaimer:
Btu listings are based on 7.0”WC for Natural Gas
and 11.0”WC for Liquid Propane (LP) at the burner orifice. Flex
line size and proper gas pipe sizing will also affect Btu’s. As a
result your Btu’s may vary slightly from Table 2 specifications.

BEFORE INSTALLING A BURNING SPUR DETERMINE WHAT PAN WILL BE USED:
The Spur Burner models above are not provided with pans for installation. We suggest you provide an appropriate non-
combustible burner pan to install the Burning Spur. Burner pans sizes listed in Table 1 are suggested sizes based on the
burning spur model size. The pans can be round, square or a flat metal.
NOTE
: It is recommended to use 304
Stainless Steel. Burner pans should have ¼” drainage holes to prevent standing water in pan and the center hole for the
burner nipple should be ⅞” in diameter. A recommended material thickness for any burner pan or disc is 16 gauge. Once
the Burning Spur is installed into a burner pan then proceed with this manual to complete the installation.
CAUTION: DO NOT use stiff screen or perforated metal as a burner pan. Some gases are heavier than air and
screen or perforated metal can enable the gas to flow down inside an enclosure which could cause delayed
ignitions or explosions.
