Macurco GD Operation Manual

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

A 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
another box unless it has good air flow through it. Do NOT mount the GD-6 where the normal ambient temperature
is below 0°F or exceeds 125°F (below -18°C or above 52°C).
High voltage terminals (120/240 VAC) are located within this detector, presenting a
hazard to service technicians. Only qualified technicians should open the detector case
and service the internal circuits. Ensure power is de-energized from the detector relays
prior to servicing the unit. Failure to do so may result in electrical shock.

3.2 Installation

3.2.1 6-Series Low Voltage

1. The GD-6 mounts on a 4" square (or 4x4) electrical box supplied by the contractor. Do not mount the GD-6
inside another box, unless it has good air flow through it.
2. Connect the GD-6 to Class 2 power supply only. It is suggested to use a separate transformer for powering
the unit or units because of possible interferences from other devices on the same power supply.
