Under certain conditions, up to 5 psig (345 mbars) is allowable on RM 300 and larger burners; contact the factory for details.
5
At the inlet to the pilot cock.
6
High fire flame length measured from the end of the firing tube, firing parallel to air flow with neutral chamber pressure. When firing
perpendicular to air flow, flame length will be shorter. Contact your local Eclipse representative for details.
