Slant/Fin Galaxy (GXH/GXHA, GXH-II and GG Series)

The Galaxy is Slant/Fin's gas cast-iron boiler family, documented across three hubs in the active 'Boilers' library section: 'Galaxy GXH/GXHA' (steam), 'Galaxy GXH-II' (water) and 'Galaxy GG Series' (water). Slant/Fin prints no 'current' or 'discontinued' sentence; section placement is the only official status wording, so Boilers.ca describes the family as current library / documents available on slantfin.com without asserting current production. A separate 'Galaxy' hub in the Vintage section covers the legacy family and is not part of this record.

The GXH/GXHA steam IOM (Pub. GGS-41 Rev. A, 419) names GXH-230, GXH-250, GXH-275 and GXH-300H with an external draft hood, and GXHA-100, GXHA-120, GXHA-160 and GXHA-200 with an integral draft diverter; all use a ½" f.p.t. gas valve, low-pressure steam and a steam controls assembly (pressuretrol, low water cut-off and gauge glass) with no electronic display or code table. The GXH-II water IOM (Pub. GXHII-42, 0121) names GXHII-95, GXHII-115, GXHII-135 and GXHII-155 — natural-draft chimney boilers with the Hydrolevel HydroStat 3200-03 control; no ratings or fault-code table is printed in the text.

The GG water IOM (Pub. GG-42, 0221) covers GG-75H through GG-399H (including the legacy GG-75…GG-225 range), a natural-draft chimney boiler with a HydroStat 3200-03/3200-Plus control and a ½" gas valve (¾" on GG-250H and up). Ratings for all Galaxy lines are on the rating plate and in official Energy Guide label PDFs that are image-only; no OCR was performed and no values were invented, so Boilers.ca keeps the Galaxy at series level with the printed model codes. No official Canadian-sales statement was found, so canadianStatus stays 'unknown'; gas, steam, venting and combustion work belongs with a licensed contractor.
