3 Installation and Operating Instructions
The following instructions are intended to serve as a guideline for the use of the Macurco GD-6 Combustible Gas
Detector. It is not to be considered all-inclusive, nor is it intended to replace the policy and procedures for each
facility. If you have any doubts about the applicability of the equipment to your situation, consult an industrial
hygienist or call Technical Service at 844-325-3050.
This detector helps monitor for the presence and concentration level of a certain
specified airborne gas. Misuse may produce an inaccurate reading, which means that
higher levels of the gas being monitored may be present and could result in
overexposure and cause serious injury or death. For proper use, see supervisor or User
manual, or contact Technical Support at 1-844-325-3050.
3.1 Location
GD-XX mounting height is dependent upon the target gas.
• If the target gas is lighter than air; methane (NG) or Hydrogen (H2), mount the GD-6 high on a wall or column
(about one foot down from the ceiling) in a central area where air movement is generally good. • If the target gas is
heavier than air; propane (LP), mount the GD-6 low on a wall or column (about one foot above the floor) in a central
area where air movement is generally good.
The unit, on average, can cover approximately 900 sq. ft. (84 sq. meters) to 1,257 sq. ft. (117 sq. meters). The
coverage depends on air movement within the room or facility. Extra detectors may be needed near any areas
where people work or where the air is stagnant. Some of the factors that affect the coverage area are application
type, personnel work areas and movement, room size, air movement, potential threat, mounting location, along
with other site-specific factors that must be considered. Please check local regulations or requirements prior to
installation. The GD-6 mounts on a 4x4 electrical box supplied by the contractor. Do not install the GD-6 inside
