Marine Installation Instructions
Before Installation
1. Check the system for damage during shipment.
2. Check the pressure gauge to be sure the gauge pointer lies within the
green zone at 70°F (21°C). The correct weight is shown on the
nameplate for the appropriate model.
3. Select an interior location not directly subject to weather or seawater.
4. Confirm the volume of the compartment to be protected in cubic feet or
cubic meters by multiplying the width in feet, by the length in feet, by the
depth at the keel in feet; make no deductions for installed equipment.
5. Verify calculated volume with volume shown on name plate label and
chart on opposite page.
Selecting a Location
1. Do not install a Fireboy system rated for less cubic volume than the
volume of the compartment to be protected.
2. Orientation:
• Mounting up to 90° from vertical is permissible
• Install on the forward or aft vertical bulkhead of the engine
compartment as near the centerline of the vessel (keel) as possible.
• Install as high as possible
• Direct the actuator towards the opposite bulkhead or towards the
engine(s)
• Avoid installing athwart ship (perpendicular to the keel) on sailboats
Mounting Fireboy system
1. Locate the lower bracket 1 ½” above the bottom of the cylinder and the
upper bracket ½” above the Fireboy nameplate. If required the 3
rd
bracket needs to be centered between the upper and lower backets.
2. Use appropriate size and length stainless steel bolts and lock washers
and bolt to bulk head or overhead.
