9.L Combustion Setup Procedure
In this section, we will explain how to set up the gas
valve so the boiler will run efficiently at both the High
Fire and Low Fire conditions.
Required tools: Screwdrivers, Torx bits, Allen
Wrench Set, Combustion Analyzer

Improper adjustment may lead to poor combustion
quality, increasing the amount of carbon monoxide
produced. Excess carbon monoxide levels may
lead to personal injury or death.
