I believe I have read in earlier posts (maybe a few thousand posts back?? HAHA!) that the KN regulator must be mounted vertically for the diaphragm to function properly.

Does the KN regulator just have to be in the vertical plane or does it have to also have the feed block valve at the 12 o'clock position? I could gain a lot of mounting room if I could mount the regulator vertically, but rotate the regulator so the feed block valve exits at about the 9 or 10 o'clock position. Will this work? Anyone done this?......

I'm still lurking out here watching this thread.

Here is a copy of Garretson's mounting instructions:

Garretson Model KN Fuel Valve Considerations

General
The KN is designed for sensitivity and simple operation. It is used with low–pressure vaporized
gaseous fuels, where dependable starting is a requirement. Because of its extreme sensitivity,
the KN offers excellent results in most remote starting applications (Standby power generators,
etc.). With proper installation and maintenance, the KN will provide years of trouble–free service.
Operation
The KN is an atmospheric zero governor which acts like the float and needle valve in a gasoline
carburetor. air–flow through a venturi in the carburetor creates a vacuum, which acts through the
outlet of the KN on the diaphragm. Atmospheric pressure then forces the diaphragm toward the
vacuum, depressing the lever and pulling the valve seat away from the orifice, which allows fuel
to flow as long as the demand persists. When the vacuum ceases, a spring force pushes on the
lever and forces the valve seat against the orifice shutting off the fuel flow. It is important to
remember that fuel should not flow through the KN when the engine is not running.
A properly adjusted KN requires a vacuum of only 0.25” to 0.35” of water column to start the
opening sequence. Due to this sensitivity, most installations do not need priming to start unless
low cranking speeds or restricted and lengthy piping are required. If priming is necessary and a
manual primer is installed, use only 1 or 2 second bursts of fuel and immediately try to start the
engine. If there is a choke on the carburetor, do not use it as this will probably cause flooding and
hard starting. As you can see, the operation of this unit is simple and basic. If you are having
trouble operating the engine, in most cases the fuel controller is not malfunctioning. There is
generally a problem with the engine or fuel supply. so do not make adjustments or attempt to
service the KN until you are sure it is needed.

Installation
The KN should be mounted as close to the carburetor as possible with the arrow on the cover
pointing up and the diaphragm in a vertical position. This helps to minimize the effects of gravity
on diaphragm travel. This unit should also be placed for easy access to the primer if provided.
There are two sets of mounting holes provided. either set of mounts will adequately support the
KN. The bottom set of holes has a 1 3/4” bolt spacing for use with all Garretson universal
mounting brackets. The mounting bosses on the cover are spaced (5 3/4”) apart for use with 5/16
bolts.
Before installing the fuel supply line, be sure that the gas pressure is no more than the maximum
inlet pressure shown on the front of the KN. If the pressure is greater, leakage could result in a
fire hazard and or hard starting. The piping to the inlet should be of sufficient size to allow full
flow to the KN. This is very important in natural gas installations as any restrictions can affect
engine performance. If a solenoid is used ahead of the KN in the low– pressure line, it should
have an orifice at least as big as the orifice in the KN. Flexible piping to the inlet should be used
to prevent cracking from vibration if the KN is mounted on the engine or other vibrating surface.
Note: Thread sealing compound should be used on all pipe thread fittings between the KN and
the fuel supply tank, being careful not to get any inside the inlet or fittings. Excess
compound could collect on the seat and orifice and cause hazardous leakage, resulting in
poor performance. After piping is complete, turn on the gas and use a soap solution to
check all fittings for leaks.
If an electric solenoid primer is used, follow the wiring and adjusting instructions furnished
separately. kit by connecting into a pressure line at a reduced pressure, call us. The KN outlet is
3/8 NPT and if an outlet fitting has not been provided, select and insert a suitable vapor fitting
taking care not to allow any chips or dirt to enter the outlet. Use of street ells or conventional pipe
fittings in the fuel line between the KN and the carburetor is not recommended as they may
restrict the flow of fuel.
Once installation of a properly sized fuel hose between the KN and carburetor is completed, if
you are installing a complete conversion return to the instructions. For field replacement
applications the unit is ready for service.
