To meet the needs of today’s fuel-efficient, downsized and space efficient burners, Webster’s popular M34DK-3 incorporates improved access to both the bleed valve and bypass plug. Locating the bleed port
plug assembly on the side of the fuel unit provides the service technician with one visible and accessible location to either bleed the fuel unit or change the bypass plug without removing the burner. The M34DK-3
retains all of the industry accepted, state-of-the-art features of the M34DJ-3 fuel unit. These include faster fuel cut-off, improved priming on one-pipe installations, and reduced inlet line flow on two-pipe systems
which results in reduced line noise. Webster’s M34DK-3 fuel unit is available in a single stage, 3450 RPM model rated at 3 GPH. Operating pressure is factory set at 100 psi and is adjustable to 150 psi. The M34DK-3 is capable of maintaining its 3 gallon per hour fire size at up to 150 psi throughout it’s service life..
