i installed a natural gas fireplace (unvented) last year with 1/2 inch
pipe coming off the main line between the main heater and the water
heater downstairs. often a surge in the line -water heater comes on
with the heater already on or vice versa - the fireplace goes out
upstairs. is there any kind of valve i can install before the fireplace
line to regulate the pressure and avoid the shutdowns? thanks, houston

Not really. The real answer is your pipes are most likely too small for the
load. Either change the pipes to a larger diameter, there is charts
available for the sizing, or see if the gas commune will boost your gas
pressure coming into the home. You will have to add regulators before each
appliance.

Greetings,

If your gas heater has different heat settings stop using the lowest
setting(s) and see if that helps. How big is your "main line" that
your space heater, main heater, and water heater branch off of? Mine
are 1-1.5" on most single family houses. How many feet does each line
run?

Hope this helps,
William
