Certification:	Maxitrol's 325 L Series regulators are CSA certified (Z21.80) for 2 psi inlet pressure, outlet pressure range of 7 to 11 inches w.c. 325-3L 325-5AL 325-7L NOTE: Installations MUST be performed in accordance with local codes or, in absence of local codes, in accordance with the NFPA 54 / ANSI Z223.1.
	The 325 Series is suitable for multi-positional mounting. But when using the vent limiting device, the regulator (325-3L, 325-5AL) must be mounted in a horizontal upright position. Install the regulator properly with gas flowing as indicated by the arrow on the casting (also see the Safety Warning Instructions bulletin).
NOTE:	Vent limiters can only be installed in regulators for which they are certified. Vent limiters must only be installed directly into the vent connection of the regulator without intermediate pipe or fittings.
