Installation Notes

Gas logs must be installed by a qualified gas installer in a solid-fuel fireplace with a working chimney, with the damper clamp holding the minimum permanent opening from the manual. Use only Peterson burners and valves with these logs. In New York City, gas piping to a fireplace requires a licensed master plumber and permit, and the chimney should be inspected before installation. Book a free design consultation and we will help you plan the layout, utilities and installation.

Frequently Asked Questions

Can I use this with propane?

R.H. Peterson's G31 manual lists the burner for natural gas only and not field convertible, so confirm any propane option with us before ordering.

Does it need a chimney?

Yes. These are vented logs for a wood-burning fireplace with a working flue, and the damper must stay open.

What size do I need?

Measure your firebox front width, rear width, depth and height and compare them to the minimums in the dimensions table.

Can I buy the logs only?

Yes. The logs-only option (CHMBW) works with an existing Peterson vented burner system.
